Design and Construction of Complex Foundations and Shallow Base for Super High-rise Buildings

摘要:

广州市淘金家园二期B5-4~7栋超高层建筑工程地下室底部置于全风化与强风化的泥质粉砂岩上，按地基土压板试验情况，设计采用天然地基与复合地基上的浅基础。由于该工程的试验、设计与施工紧密配合，施工措施可靠，成为广州市超高层建筑采用复合地基和浅基础的成功实例。介绍其试验情况、设计思路、施工要点和实施效果。

Abstract:

The bottom of basement of Super High-rise Buildings B5-4~7, which are the part of Guangzhou Taojinyuan, was located on completely weathering and strongly weathering powder sandstones. According to the results of soil press test, the shallow base which is on the top of natural or complex foundations was adopted in design. Because of putting experiment, design, work into a very closed link, as well as the method of work is trustworthy, it has been the succeed case of super high-rise building in Guangzhou City. The experiment conditions, design conceptions, project main points and application results were introduce.
