为解决普通民用建筑因地下水位回升引发的工程问题，针对监测数据和理论依据不足的实际困境，本文构建了一套针对地下水位在岩溶承压水顶托补给作用下快速回升的过程中与区域内建筑物及地层相互影响的“流-固”耦合数值模拟方法，并运用该方法分析研究了邢台百泉泉域排泄区地下水位快速回升过程中对建筑物影响机制。结果显示:邢台百泉泉域排泄区内地下水位快速回升过程中，建筑物产生垂直向上位移，最大达38.11 mm;地下结构墙体与底板连接位置出现拉应力集中，达到1.88 MPa，接近C30混凝土抗拉强度限值2.01 MPa，可能使结构由弹性向塑性变形转化，导致拉裂缝产生，为建筑物出现渗水、漏水的重要原因之一。研究表明，地下水位快速回升可能导致建筑物变形活跃及结构应力集中。
Abstract：To solve the engineering problems of ordinary civil buildings caused by groundwater level rise,and aiming at the practical dilemma of insufficient monitoring data and theoretical basis,this paper constructed a set of “fluid-solid” coupling numerical simulation methods to study the interaction between the rapid rise of groundwater level under the uplift and recharge of karst confined water and the buildings and strata in the region. This method is used to analyze the mechanism of influence on buildings during the rapid rise of groundwater level in the discharge area of Xingtai Baiquan Spring Basin. The results show that during the rapid rise of groundwater level in the discharge area of Xingtai Baiquan Spring Basin,the buildings generate vertical upward displacement,with the maximum reaching 38. 11 mm,tensile stress concentration occurs at the connection between the underground structure wall and the bottom floor,reaching 1. 88 MPa,which is close to the tensile strength limit of C30 concrete( 2. 01 MPa). This may cause the structure to transform from elastic to plastic deformation,resulting in tensile cracks,which is one of the important reasons for water seepage and leakage in buildings. The study indicates that the rapid rise of groundwater level may lead to active deformation of buildings and structural stress concentration.
