摘要
本文提出了确定桩土应力比n值的K值修正法以及用K值修正法与动力触探DPS、静力触探CPT试验综合评价碎石桩加固软弱地基效果的新途径。通过对6个工程实例的研究分析,K值约为1.12。
The paper presents a method to determine the stress ratio in .the composite foundation of gravel piles modified with value k. In combination with dynamic penetration test and cone pentration test,the improved effect of the soft ground with gravel piles can be estimared. After analysing six engineering examples, the value K approximates to 1. 12.
