武林水闸消除闸基底拉应力的加固方案选择

Selection of Reinforcement Scheme against Tensile Stress at Gate Basement of Wulin Water Gate

主要针对长洲水利枢纽工程库区武林水闸混凝土闸坝基础存在拉应力这一现象,根据现场和工程实际情况,通过优化比选后采用比较简单的以混凝土培厚的施工方案,使基础拉应力得以消除。加固方案对其他类似工程项目具有借鉴意义。

Tensile stress is found at concrete foundation of Wulin water gate at the reservoir area of Changzhou Hydraulic Complex, and is cleared up through thickening concrete after scheme comparison under the practical conditions of the site and the project. Such reinforcement scheme may be learnt by other projects of this kind.
