摘要
在土建、交通、水利等工程建设中经常遇到的软弱地基,软弱地基处理方法层出不穷,许多经济、快速、有效的实用的方法在工程中已得到较广泛应用,粉喷桩复合地基就是这类方法中较典型的一种。结合固镇新湖沟涵工程,对工程中所用的粉喷桩进行静载荷试验,并采用有限元法对粉喷桩单桩复合地基进行数值计算,所得计算结果与实测数据基本吻合。
With the development of China＇s economy and the growing scale of China＇s infuastructure construction, more highways, bridges, houses, etc. need to be built on the soft ground. There are various methods for managing soft ground, and many economical and effective methods have been widely used in engineering, Dry Jet Mixing method is one of them. In this paper, the static loading test is done to the DJM piles which are used in the Xinhugouhan Engineering in Gu Town, and the numerical evaluation calculation on the single dry - cement Jet mixing pile composite foundation is made by means of the finite element method （FEM）. A good agreement has been found between the results of finite element calculation and measured data.
