复杂地质条件下某深大基坑降水方案优化设计

Optimum Design of Dewatering Scheme for a Deep and Large foundation Pit under Complex Geological Conditions

降水技术对地下空间开发利用影响最为严重,因此,必须深入研究深大基坑降水技术,优化降水方案,从设计入手,从实际出发,保证在复杂地质条件下安全可靠的推进深大基坑工程,保证深大基坑工程的质量,提高深大基坑工程的实用性能。通过深入了解深大基坑降水技术的发展现状,分析复杂地质对深大基坑降水方案设计的影响因素,并通过分析深大基坑的结构,进一步完善深大基坑降水方案。

The influence of precipitation technology on the development and utilization of underground space is the most serious. Therefore,it is necessary to study deeply the dewatering technology of deep and large foundation pits and optimize the dewatering scheme. Starting from the design and practice,we should ensure the safe and reliable promotion of deep and large foundation pits under complex geological conditions,ensure the quality of deep and large foundation pits,and improve the practical performance of deep and large foundation pits. This paper,through in-depth understanding of the development status of dewatering technology of deep and large foundation pits,analyses the complex geological conditions. The influencing factors of dewatering scheme design of deep and large foundation pits are analyzed,and the dewatering scheme of deep and large foundation pits is further improved.
