摘要
在桩土应力比计算水泥搅拌桩复合地基承载力理论基础上,提出了利用桩土平均瑞利波速评价复合地基承载力的一种新思路,并利用数值分析的方法验证了这种思路的可行性。
In this paper, a new thought was given to appraise improvement effect of composite foundation by use of average velocity of Rayleigh wave of pile and soil, based on the principle of calculating the bearing capacity of cement mixed pile composite foundation by means of stress ratio of pile and soil. Moreover, feasibility of this thought is validated by using a numerical analysis method.
