低洼地区建筑的抗浮设计与设防水位合理确定

针对低洼地区建筑抗浮设计不准确,设防水位不合理的问题,提出一种新的低洼地区建筑抗浮设计和设防水位确定方法。在分析工程所在的低洼地区地下水位分布情况及其所要承受的浮力值基础上,以某低洼地区建筑项目为例进行了详细的分析,给出了项目工程概况、所处位置的地质和建筑基础形式,提出了适合此项目的抗浮方法,并经过试验分析发现,在此项目中选择使用板下集中布桩的方式进行抗浮设计,在加上锚杆配筋及板内力计算确定了锚杆布置方式,增加了抗浮性能;同时设防水位取值分别为潜水水位埋深值约2.37 m,承压水水位埋深值约10.42 m时,为最合理,性能最优。

Low-lying areas building anti-floating design and fortification level are established

In low-lying areas building anti-floating design is not accurate, fortification level unreasonable problem, put forward a new kind of low-lying areas building anti-floating design and fortification level determination method, based on the analysis of engineering in the low-lying areas of the distribution of the underground water level and have to withstand buoyancy value basis, in a building project, for example has carried on the detailed analysis, project engineering general situation is given, the location of the geological and construction foundation forms, anti-floating method is proposed for the purpose, and through the test analysis found that choose to use in the project board anti-floating design in the form of concentrated cloth pile under combined with calculate and determine the internal force of the anchor rod anchor reinforcement and plate arrangement, increased the anti-uplift performance, at the same time fortify level values respectively submersible water depth value of 2.37 m, confined water water depth value of 10.42 m, for the most reasonable.
