摘要
振动挤密砂石桩复合地基的应用已取得较好效果,但其上部常存在软弱土层或夹层、厚薄不一,直接影响了该方法的推广和效应。本文介绍采用换层振压密实或补偿基础的处理方法,并经工程实践,通过静载试验、标贯试验、静力触探等手段验证了实际效果。
The application of sand-stone vibratory compacting pile composite foundation has been very effective. But on the top of the foundation sandwich or weak soil varying from thin to thick often exists, this has direct influence on the efficiency and expansion of this method. This paper introduces a method using stratified vibratory compacting or compensating foundation. After being adopted in projects, the actual effect of this method is proved by static load tests, standard penetration tests, and static penetration tests etc.
