摘要
Abstract
The authors mainly introduce the method of determining the bearing capacity of dam foundation rock mass in a project in the Philippines,and compare it with the method of determining the bearing capacity of dam foundation rock mass in China,and analyze the difference between the two.This method uses Hoek-Brown strength criterion to obtain the shear strength parameters of dam foundation rock mass,and then calculates the bearing capacity of dam foundation rock mass with reference to EM 1110-1-2908 Rock Foundations,which is recognized by the owner's consulting engineer.By comparing the value methods of rock mass bearing capacity at home and abroad,it is found that the calculation results of each method are comparable.The main difference is that the value method of American standard is applied to rock mass based on the theory of Terzaghi soil mechanics,while the value method of domestic standard is based on engineering experience.It is expected that this method can provide reference for similar projects abroad.关键词
