| Abstract: | For plastic concrete,due to its stronger adherence to sand and stone base and its lower elastic modulus, and its better deformation performance,it is used in cutoff wall. In order to monitor the plastic deformation security of the cutoff wall, a test was carried out for the first time in Xiaojiang reservoir of Guangxi Autonomous Region,the strain and stress of the cutoff wall were measured with optical fibre gauge. And some precious experiences were attained in the optical fibre layout method and the analysis of deformation performance of plastic concrete. |
