Abstract

Currently，the in situ rock mass mechanical test technology is still in the backward status of manual loading and unloading and artificial recording. To cope with this issue，the servo control and data acquisition system for in situ rock mass mechanics test have been successfully developed. It′s operational principle，structure characteristics and key techniques are introduced. The system has such noticeable features as follows：automatic servo control and data collection during whole test process with high precision；high reliability and stable performance；simple instrument operation and convenient data processing after the experiment；application to all kinds of in situ rock mass mechanics test with prominent advantages. This system is used to carry out 6 points deformation test and 12 points direct shear test of rock mass for two-mica schists of water diversion system of Danba hydropower station in the Dadu River. It gets the whole process curves of deformation test and direct shear test of rock mass. The experiment results show that two-mica schists have significant characteristics of anisotropy. This system provides a new method for researching the deformation and strength characteristics of complicated engineering rock mass.

Key words： rock mechanics；in-situ rock mass mechanics test；servo control；automatic collection；development and application
