摘要
厦门花岗岩风化残积土分布广泛,厚度达10—50米,对其工程地质性质一直缺乏系统、全面的研究,地基承载力也是将其简单地归为某一类土,查规范、手册求得,所得结果常常不够准确。作者在经过几年的工作,进行了详细的野外勘察、野外及室内试验,收集了大量第一手资料的基础上,对整个残积土层的组构特征、物理力学性质作了总体、系统地阐述。根据静载荷、微载荷及旁压实验,探讨了残积土承载力的规律性以及与标贯击数的关系。
Granitic residual soil covers a large part of Xiamen island. Its thickness ranges from 10 to 50m. Based on a number of firsthand data from in situ investigation and in situ or lab tests, the authors synthesized its fabric characteristics and physical mechanic property. The paper introduces in situ plate bearing capacity-pressuremeter and lab minor bearing capacity test and lateral pressure test on residual soil. The correlation between bearing capacity and SPT N values of residual soil is established.
