摘　　要：采用钻探、超声波测井、抽水试验、水质分析、地微震测量、室内岩土力学室验等综合勘探测试方法,确定薄至中厚层状泥质白云岩、泥质灰岩夹泥岩、页岩组成的软质岩与硬质岩互层状岩体地基承载力特征值,结合地区的建筑经验合理的评价和充分挖掘软质岩与硬质岩互层状岩体地基承载力特征值(fa)和基坑边坡设计参数C、Ф。By using such explorations testing ways as drilling, ultrasonic logging, pumping test, water analysis, microseismic survey and indoor earth mechanical experiments, the foundation bearing layer＇s features in soft rock iterbedded hard rock constituted by argillaceous dolomite rock, argillaceous limestone, pelitic mudstone and shave rock was detemained. The foundation bearing layer＇s features（fa） and the slope design parameters of C andΦin foundation pit was evaluated and excavated through local architectural experience.
