桥梁群桩基础沉降特性与计算方法

Characteristics of Settlement and Calculating Methods about Bridge Pile Groups Foundation

由于群桩基础受多方面的影响和作用,使其受力状态非常复杂,目前它仍是岩土工程领域的研究热点。简要阐述群桩基础的沉降特性,然后对群桩基础常用的沉降计算方法进行详细论述,并对各种方法进行相应的评价。

The bearing state of plie groups foundation is very complax which is influenced and effected by many aspects. Therefore, at present it is still the research hotspot in geotechnical engineering field. Firstly, the settlement characteristics of pile groups foundation are expounded in brief. Then its settlement calculation methods in common use are discussed in detail. At the same time, every method is evaluated.
