印度尼西亚PosoI水电站覆盖层物理力学性状研究

在印度尼西亚PosoI水电站前期设计工作中，由于业主提供的资料较少，使得对工程区覆盖层物理力学特性的分析和工程地质条件的掌握上存在困难。为了解决工程问题，进行了现场地质调查工作和钻孔岩心重新鉴定工作。根据现场地质调查、钻孔资料和孔内试验资料，结合中国工程经验，采用工程类比法综合提出了适合本工程的覆盖层物理力学参数。本工程中工程问题的解决方法值得类似的国外工程借鉴。

STUDY ON THE PHYSICAL AND MECHANICAL PROPERTIES OF THE OVERBURDEN OF POSOL HPP IN INDONESIA

In early stage of design work of PosoI HPP in Indonesia, the data provided by owner was less. It's hard to analyze the physical and mechanical properties of overburden and the engineering geological conditions. In order to solve the engineering problem, the field geological survey and borehole core appraisal have been carried out. According to field geological survey and analysis of borehole test data provided by the Owner as well as actual experience in China's projects, we have used engineering analogy method to propose recommended values of physical and mechanical parameters for overburden in the project area. The solution of engineering problem is worthy of reference for the similar project abroad.
