水泥土搅拌桩单桩载荷试验竖向承载力特征值确定方法的探讨

Approach the method to determine the characteristic value of vertical bearing capacity during the test of single cement-soil composite pile load

本文提出按s/d确定水泥土搅拌桩单桩载荷试验竖向承载力特征值的方法,其优点是直观可靠,便于整个工程评价。但现场试验时,观测精度要求较高,尤其是桩头处理要求细致认真。

This paper presents the method base on s/d to determine the characteristic value of vertical bearing capacity during the test of single cement-soil composite pile load. The advantages of the method are perceivable, reliable, and easy to evaluate the whole engineering project. However, the requirements of observation accuracy are high, especially the treatment of pile cap should be careful and earnest on the test site.
