砂石桩与低强度混凝土桩组合型复合地基在软土地基中的应用(一)

The Application in the Soft Soil Ground of the Composite Foundation of Sand -stone Pile and Concrete Pile with Low Strength

本文通过试验与工程实践，介绍采用碎（砂）石桩及低强度混凝土桩组合构成复合地基的试验成果、计算方法及应用检测成果。组合型复合地基可发挥两种不同刚度加固体在复合地基中各自的特点，经济技术效益明显，应用效果良好。

This paper introduces the test results and calculative method by using the composite foundation of sand-stone pile and concrete pile with low strength. This composite foundation can develop the properties of two kinds rigidity stabilized body. It has obvious economical and technical benefit and good applicable results.
