摘要

结合一个典型的工程实例，综合分析和比较了室内岩土试验和原位试验结果对岩石地基承载力设计取值的影响。提出在复杂地质条件下按室内岩土试验的结果比按经验取值偏低，以原位试验的试验结果确定地基承载力更为科学、合理。通过原位试验确定地基承载力和变形模量，用原位试验的变形模量计算建筑物的沉降，并与实测值进行比较，两者结果非常一致。

Abstract

Using a typical construction project as an example

a general analysis and comparison are executed to the influence upon the determination of the bearing capacity of rock foundation from the laboratory test and in-situ loading test of rock. A conclusion is drawn that the measurement with data from the result of laboratory test of rock is lower than the data from experience

while applying the result of in-situ loading test of rock to measure the bearing capacity is more scientific and reasonable. According to in-situ loading test of rock

determinating the bearing capacity and modulus of deformation of the rock

and then calculating the settlement of the building with obtained modulus of deformation

the result shows that it is very consistent with the observations.
