摘要:
基于优化设计的目标函数法,以控制点水位为首要约束条件,总排水量最小为目标函数,采用Excel软件"规划求解"模块对地铁隧道管井井群降水设计进行优化分析,获得降水影响范围、降水井合理布置方案及单井排水量等指标,实现了满足施工要求的总排水量最小的目标。采用该优化方法分析沈阳地铁张沈区间的工程降水实例,优化方案总排水量为18552.6m3/d,比采用潜水完整井公式计算结果减少约5%,经现场水位监测获得降水水位曲线,证明优化方案能满足施工要求,经济合理。
Abstract:
Multi-well dewatering for a subway tunnel is optimized using the Excel software based on optimal objective function and with the primary constraint conditions of groundwater level at the controlling points and the target function of minimum drainage flow.The influenced range of dewater,locating project of dewater well and drainage of a single well are obtained,and the target of minimum drainage flow is also obtained.Dewatering in the Zhangshen tunnel is analyzed with the optimization method.The influenced range of dewatering and the optimized drainage(18 552.6)m~3/d is reduced by 5%,lower than the result calculated with the model of a fully penetrating well in an unconfined aquifer.The dewatering curve is obtained and compared with the simulated finite element analyses and the optimal design is confirmed to be reasonable.
