亦庄调节池取水口及连通闸闸室稳定计算

The stability of sluice chamber of water intake and connectivity sluices in Yizhuang regulation pool

为保证亦庄调节池（一期）工程中亦庄取水口、永乐取水口、1号和2号连通闸闸室的稳定性和安全性，根据水闸规范相关规定，利用Excel表格，针对四种工况进行闸室基底应力和抗滑稳定计算。经过计算和分析：亦庄取水口和2号连通闸闸室地基承载力不满足设计要求，需要对基础进行换填砂砾料处理。在施工过程中根据详实的钎探检查结果，由地质工程师指定具体的换填位置和土层换填厚度，换填碾压合格，经地质工程师确认后方可进行下一步施工工序。闸室结构的稳定计算分析为提高亦庄取水口、永乐取水口、1号和2号连通闸闸室的稳定性，保证水闸的正常运行，及整个亦庄调节池工程的安全性提供了有效保障。

According to the relevant provisions of the sluice specification, using Excel spreadsheet, chamber base stress and sliding stability are calculated in four kinds of working conditions,in order to ensure the stability and security of Yizhuang and Yongle water intake sluices,1# and 2# connectivity sluices of Yizhuang regulation pool（the first phase of construction）. After calculation and analysis, Yizhuang water intake and 2 # connectivity sluices do not meet the design requirements of the bearing capacity of foundation of sluice chamber, the foundation needs to deal with replacement of sand gravel material. During the construction process, according to the detailed drilling results, geological engineer specifies the replacement position and soil replacement thickness, after the replacement of foundation treatment, the next step can be carried out by geological engineer confirmed the results. These improve the stability of sluice, ensure the normal operation, and provide effective protection of the safety of the whole project.
