摘要
塑性混凝土与砂石地基结合性好,弹性模量低,用作防渗墙具有较好的变形性能。为了监测防渗心墙塑性变形的安全性,在广西小江水库首次运用光纤应变计进行塑性混凝土心墙的应力应变测试,初步取得了在埋设工艺和分析研究变形性能等方面的经验。
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.
