| 摘 要： | 地面沉降是一种典型的环境地质现象, 它严重影响了社会经济的发展, 阻碍了城镇化进程。本文基于山东省淄博市境内的黄金国际重点建设工程, 为评价此工程受地面沉降的影响程度, 以拟建工程区及外围0.6km2区域内40余米厚的第四系松散地层为研究对象, 根据地层的工程地质特性, 逐一划定压缩层, 并且基于一维固结理论及岩土压缩系统方法, 分别计算受水源地开采影响及在不同地面荷载情况下, 工程建设区的地面沉降量, 并对其发展趋势作了合理的预测。研究结果表明, 水源地开采及建筑物荷载综合作用诱发的地面沉降对工程建设的影响程度有限。该项工作, 一方面为该工程建设提供决策依据, 另一方面, 为受类似地面沉降问题影响的工程建设提供参考。此外, 针对山东省淄博市境内地下水开采及建筑物荷载综合作用下的地面沉降研究, 以指导其规划和建设, 有益于科学、快速、可持续发展。

| Abstract: | Land subsidence is a typical environment geological problem. It seriously affects the development of social economy and the process of urbanization. This article based on the key construction project of Golden International in Zibo, Shandong Province. To evaluate the impact of land subsidence on the project, the Quaternary formation, which is about 40meters thick and located at the 0.6km2 proposed project area, was taken as the research object. According to the engineering geological characteristics, the formation was divided into four compression layers. Considering respectively groundwater exploiting in ZhangXi water source field and different building loads, the amounts of land subsidence in the area of the construction project were calculated and the trends were predicted based on one-dimensional consolidation theory and geotechnical consolidation approach. The result showed that land subsidence due to groundwater withdrawal and building load had less impact on the construction project. The study helps making a basis decision for the construction project, and also provides a reference for constructions where are affected by land subsidence. Besides, the study of land subsidence due to groundwater withdrawal and building load in Zibo city of Shandong provice will guide the planning and construction of the city, it can benefit it sciencely, rapidly, sustainable developing. |
