浙江温黄平原地下水控采后地面沉降效应分析

Ground subsidence effects since groundwater exploitation restriction in Wenhuang plain

通过收集整理相关检测数据,分析浙江温黄平原地下水控采后的地面沉降特征及发展趋势。结果表明,随地下水大幅减采,地下水位回升明显,地面沉降同步快速减缓,由区域性沉降转变为局部工程性沉降,认为工程性沉降监测防治是今后温黄平原地面沉降防治工作的重点。

Based on the collection and analysis of some relevant data,we discuss the ground subsidence characteristics and development trends,ever since the measures of groundwater exploitation restriction had been carried out in the Wenhuang plain,Zhejiang Province.The result shows that underground water levels has gone above significantly along with groundwater exploitation significantly reduced,and ground subsidence has turned regional subsidence into local engineering subsidence.It is concluded that engineering subsidence monitoring is important in controlling ground subsidence in the Wenhuang plain from now on.
