【摘要】 随着地下工程的蓬勃发展,由地面沉降引发的建筑物开裂等灾害也日益增多,降水是引发地面沉降的主要原因已得到大家的共识,然而其中的机理却依然复杂,因此,本文从地下水动力学降水涉及变形的理论公式的角度对降水引发地面变形机理进行探讨,考虑了时间因素的影响,最后对一个工程实例进行了应用。更多还原

【Abstract】 With the rapid development of underground engineering,building cracking and other disasters caused by ground subsidence are increasing. Dewatering is the main cause of ground subsidence,which has been universally accepted,but its mechanism is still complicated. Therefore,this paper used the theoretical formula of deformation and dewatering in groundwater dynamics to study the mechanism of ground subsidence caused by dewatering. Additionally,time factor was taken into consideration. Finally,this mechanism was applied in an engineering case.更多还原
