Abstract: Study on the on-site deformation test of rock mass in Tianxing reservoir// by WANG Honghang// Gansu Water Resources and Hydropower Survey, Design and Research Insitute Co., Ltd.
Abstract: During the survey and design of Tianxing reservoir dam, a detailed analysis of geological con ⁃ ditions is conducted, and on-site test of deformation of dam foundation rock mass is conducted. The test results  show  that  there  are  three types  of deformation  curves  of dam foundation  rock  mass,  namely straight line, upward convex and downward concave. As well, the closer to the tunnel face, the more the rock mass integrity improves, and the deformation modulus and elastic modulus of rock mass show a gradually increasing trend. The test results provide a theoretical basis and data support for the survey and design of the reservoir dam, and provide important references for dam filling construction, which is of great significance in construction engineering.

Key words: survey and design, deformation of rock mass, deformation curve, deformation modulus, elas ? tic modulus
