摘要: 某热电厂海水取水泵房基坑工程地质条件复杂,紧邻丘陵山体,基岩面起伏较大。根据工程特点,考虑围护结构安全、对环境和施工工期影响等因素,对基坑围护结构方案进行综合比较,采用冲孔灌注桩加两道钢箱梁内支撑的方案,并采用高压旋喷注浆形成止水帷幕。整个施工过程和监测结果表明,该基坑工程方案是可行的。Abstract: The excavation project for the pump room of a thermo-electric plant is close to hills. Its geological and environmental condition is complicated,which is disadvantageous to its design. According to the safe principle and convenient construction,punching cast-in-place concrete pile and steel box girder were adopted to support the structure. And the high pressure jet grouting was used to act as waterproof heavy curtain. Through the whole construction and monitoring result,it is shown that the design is reasonable.
