浅析北京地区建筑抗浮设防水位的影响因素

Analyses the Influence Factors of Building Groundwater Level for Prevention of Up-floating in Beijing Area

对影响建筑场地地下水水位动态变化的各种可能因素及其影响程度进行分析,是论证和最终确定安全、经济、合理的建筑抗浮设防水位的基础。对建筑抗浮设防水位的各种影响因素进行分析,探讨各种影响因素对预测拟建场地地下水水位动态变化规律、发展趋势和对确定建筑物基底处地下水水头压力大小及建筑抗浮设防水位值的作用。

The analysis and research on all possible factors and influence degrees of the groundwater dynamic change of building site is the important foundation of the security, economic and reasonable building groundwater level for prevention of up-floating. In this paper, to research and analyze various influence factors on the building groundwater level for prevention of up-floating, to discuss the effects of various factors on the predicted groundwater level dynamic change rule, development trend , the basal groundwater head pressure and the groundwater level for prevention of up-floating value of building.
