泰州长江大桥地基砂性土压缩模量确定方法

摘要

Aiming at the problems encountered in the deep foundation prospecting for Yangtse River Bridge of Taizhou, the comprehensive test method integrating the laboratory test with the in-situ test by static sounding and lateral pressure test is expounded and the determination method for modulus of compression of coarse-grained sandy soil under the condition of actual stress of common and over deep foundations has been studied byusing the relationship between bearing capacity and the compressive index in accordance with the regulations of the standard code in order to solve the key problems of calculation for bridge settling deformation.%针对泰州长江大桥深基础勘察中遇到的问题,阐述室内试验和原位测试静力触探、旁压试验相结合的综合试验方法,并通过规范规程中承载力和压缩性指标的关系,研究常规和超深地基实际应力条件下粗粒类土压缩模量的确定方法,解决大桥沉降变形计算中的关键问题.
