～～全新韩国地基工程技术，免打桩～～ 40楼工程新图

还我言论自由

哈哈，没人询问，询问度不高？

这里的工程师不敢用哟？

如果可用来顶到三十层而不用piling，也不用raft ，肯定是地质学的壮举了!!!
接下来我看很多borepile老要吃草了。我也是其中之一。
看来这次真的要去投靠Mr. Jacky Khoo了。

强烈建议Mr. Khoo upload几张有关这个产品的research report或 journal paper。不是自己website的或大学大炮一下就可以了。

## 有点好奇，既然这样好料，怎么新家波的韩国main-con不带进来呢？哈哈。。

我在新加波好几年了，也看了不少韩过的技术如DSM, Diaphragm Wall Technology or PVD installation ....唯独少了这样.

刚看了贵公司website 的 video, 请问你那个 one basement and five storey 的 factory concrete slab （so called " top-base" ）有多厚？和普通 RC slab 有什么差别？cost saving 在哪？material cost? or labour cost?

如果你不明白，或者不了解，可以到我公司网站www.topbasemethod.com ，在DOWNLOAD 哪里有一些教授级人物的分析资料，你可以了解一下，
东西呢不懂，不代表不好，不可以用，除非你说你是这方面的权威，可惜你不是。
里面有一些资料，或者也可约个时间，我可以向你讲解，BORE PILE是有它自己的市场，
但是我的系统跟BORE PILE完全不一样，

不好意识，BORE PILE不是PATENT 的技术，我代理的是PATENTED，所以新加坡和
马来西亚只有我独家。

Top-base Cone 有500mm厚，加SLAD150mm-200mm,大概有650-700mm,
factory slab( m2 cost )= piling cost + ground bean & slab= RM 70  + RM 250  (conventional piling system)               = RM 320

                                      =top-base + slab                             =RM 150 + RM 70   ( Top base foundation system)            =RM 220

差别100元马币

jackykhoo77

想了解了解你的saving是compare哪一种foundation? 感觉上如果是raft foundation 的话应该不多吧。
crazy_old_men 发表于 2-11-2011 08:49 PM

谢谢您的关注，这要看你的承受设计还有土质报告SI,
然后我在做一些比较，这样会比较好。

老兄，韩国HYUNDAI CONSTRUCTION, SSANGYONG CONTRUCTION，DAEWOOD, POSCO......等等都是我们的客户。

SSANGYONG Construction Singagpore在圣淘沙的超级豪华住宅（reclaim land)在去年已经邀请我们去做了，
只是来不及参与。

等等都是我们韩国母公司的客户,需不需要我POST PROJECT REFERENCE 给你看？

RC RETAINING WALL AT BAHAU

坦白讲，对你的project reference的是没什么兴趣。不用看都知道要讲什么东西。
还是比较有兴趣知道这个产品的technical research，或想关的journal paper  。最好是关于如何用finite element来model你的product，用什么soil model之类的。希望你明白什么是modeling, soil model和finite element。

如果不明白的话，也不想在这跟你纠缠不清。不是说找个Ir签名就了事或者说适合任何SI。
还有请不要把geotech看得这么简单和straight foward，会侮辱很多geotech界的精英。
我想做过geotech的人都同意我讲的这句话！

关于井底之蛙，我看未必。小第在新马这带应该也有做超过十五场的sub-structure了,from design until completion stage。for piling，从100mm的micropile做到3000mm的boredpile,从五米钻到九十米，从marine clay做到granite。for diaphragm wall，也是一样，从十五米做到五十米，从做600mm到1500mm，从四方的做到圆型的。for barrete pile，什么型都做过了，长形，方形,H-形,十字形。。。
做strutting system, single strut, laced sturt, triple laced strut, deck for service crane or borepile rig- BG36,concrete strut, full top-down, semi top down。。。做structural system including 2.5m thick raft, 4000m3 giant pilecap, 3.0m x 2.4m x 18.0 giant transer beam with multi-stage post-tensioning....


最后希望将来你的产品可以大卖！

p/s:其实从商业角度我应该不可跟你吵的，因为我现在就在kl做geotech freelance desinger，搞不好还要跟你拿工来做了， 哈哈。。。

bangsaruoa 发表于 8-12-2011 12:15 PM

我非常赞同你的经验，老实说，在新马，这是新的系统，没什么人知道，所以不能怪你，对于你的工作经验，我可以说非常齐全，只不过这些也是新马两地的固有系统，


但是老兄，如果你真是Geotech里面的精英，你应该去了解这日本及韩国的技术，

我网站里面（www.topbasemethod.com)的download,你认认真真的去看里面日本Geotech和韩国的前辈的研究，
资料非常齐全，这里写，要写几十面，我懒惰。
还有1987年度的KOBE university 所主办的国际研讨会的技术报告，韩国DANKOOK UNIVERSITY geotech research centre
的研究资料......

看了你才来评论，如果你是比这些教授级别精英中的精英还精英的话，你说不能用，我也没有办法。

在此也祝贺你，新的一年，PROJECT接不完，生意兴隆！

其实这也不算新产品，可算是geosynthetics的一种吧？用来support low rise building我看应该是可以，曾经都有人用bamboo来做soil reinforcement。
至于这个statement
{ 没问题，其实根据SI，有时候可以建到30层的建筑物}，
真的是要十分小心。希望没有人被误解。high rise要考虑很多的！如 differential settlement, lateral wind loading，torsional moment, high punching shear at column area..... 不知各位大大有何高见？

在2005，Ssangyong Park Regency Builidng (30F, with 3 floor basement carpart), 就是用我们的地基系统，在韩国。

想问下：

请问你的服务是我们给你working load,
然后你再帮我们design?
还是我们需要自己design?

Dragoon 发表于 17-12-2011 10:31 AM

design load 是你们Concsultant给的，因为每个建筑用途不一定，然后再根据SI，计算出original bearing capacity of ground

and after Top-Base system ground bearing capacity, 还settlement.

完工后的RETAINING WALL

Retaining wall 计算方程式：

(1) Design Load
Effective ① Width : B' = B-2×eB = 4.60-(2×0.45) = 3.70m
② Required Design Load : q = ΣV/B' = 49.867/3.70 = 13.480t/㎡
(2) Bearing Capacity of Original Ground
qa = (1/F) { α(2/3)cN'c + βϒ1BN'r + P0N'q }
A = B × L = (B′=4.60-2eB=3.70m)×1.00m/m = 3.70㎡/m
At foundation shape ; α = 1.0+0.3B′/L = 1.0
β = 0.5-0.1B′/L = 0.5
F = 3, ϒt = 1.70t/㎥, c = 4t/㎡, Ø = 10°
Po = ϒ2Df = 1.70×0.85 = 1.445t/㎡
At θ = 0° and Ø = 10°, N'c = 8.01 , N'r = 0.00 N'q = 1.94
= (1/3) × { 1.0×(2/3)×4×8.01 + 0.5×1.70×3.70×0.00 +1.445×1.94 }
= 8.054t/㎡ 〈q = 13.480t/㎡ ∴ N.G
(3) Bearing Capacity of Top-Base(Ø500㎜-1Layer) Method
qka = (1/F) K1K2 { αcNc + βϒ1BkNr/2 + P0Nq }
AK = BK × LK = (B′K=2.50-2eB=4.10m)×1.00m/m = 4.10㎡/m
At foundation shape ; α = 1.0+0.3B/L = 1.0
β = 1.0-0.4B/L = 1.0
F = 3, ϒt = 1.70t/㎥, c = 4t/㎡, Ø = 10°
Po = ϒ2Df = 1.70×(0.85+0.50) = 2.295t/㎡
At θ = 0° and Ø = 10°, Nc = 8.00 Nr = 0.53 Nq = 2.50
K1 = (Bk+2Htanω) / B'k
= (4.10+2×0.50×tan30°) / 4.10 = 1.141
K2 = ( Clay soil ) = 1.2
= (1/3)×1.141×1.2×{ 1.0×4×8.00 + 1.0×1.70×4.10×0.53/2 + 2.295×2.50 }
= 18.066t/㎡ 〉q = 13.480t/㎡ ∴ O.K

Recently a new foundation method which is called TOP‐BASE METHOD has attracted
engineers attention in Japan and Korea. It is used on very soft ground to reduce the
consolidation settlement and to increase the bearing capacity of a foundation.
The Top‐Base method is to locate top‐shape concrete blocks on/in a thin graveled
mat laid over very soft ground. In‐situ measurements of the behavior of the
foundations indicate that consolidation settlement is reduced up to 1/2~1/10 or more
and bearing capacity of the foundation increases 50%~200% or more comparing to
the primary non‐treated ground.
It is found so far that the Top‐Base foundation prevents the lateral deformation of
soft ground and reduces its negative dilatancy to reduce the surface settlement, and
that the foundation creates rather uniform stress distribution under it to increase its
bearing capacity.
With the increasing of population and the lack of land, even a very soft ground has
to be used for a regident place in Japan and Korea. Therefore, civil engineers are
required to improve such a soft ground for the construction of structures in judging by
reliability, handling capability and cost performance in case that a structure is not very
heavy, it can be built safely only with proper improvement (without piles) of the near
surface and/or subsurface ground.
Recently a new method has been invented which assembles the top‐shaped concrete
blocks and places them on the ground. A group of the top blocks can be used as a
shallow foundation replacing the piles. It is called "Top‐Base Foundation". It has been
reported that many real structures constructed with the new method show drastic
effects of reducing settlement and increasing bearing capacity of the structures.
Innovative foundation method, Top‐Base, has been improved and applied on soft
ground successfully more than 10 years in Korea. There are two kinds of Top‐Base
foundation which one is the Factory‐made Top Base ‐ and another is the In‐place
Top‐Base. Even though Factory‐made Top‐Base and In‐place Top‐Base are same
functions, In‐place Top‐Base is more easier in handling capability and is more
cheaper in cost performance than Factory‐made Top‐Base. So, most engineers
recommend the In‐place Top‐Base Foundation which is developed and improved by
our firm Banseok Top‐Base Co.,Ltd.
