Use of Rrtificial Recharge to Rectify Adjacent Building Deformation due to Dewatering
Uncontrolled, unreasonable foundation pit dewatering is often the primary cause of deformation of nearby buildings. It is therefore imperative to diminish or eliminate the negative influence during dewatering. This paper describes the application of artificial recharge to rectify adjacent building deformation due to pumping. Bases on the principle of potential function superposition, a water line equation with pumping and injection wells steady or unsteady simulations operate in a confined aquifer are deduced, thereby an influence radius concept for unsteady flow is proposed. Through a project example, the control effect of recharge for nearby building deformation due to pumping is evaluated, results of which confirms that recharge can be used as an effective management methods. Moreover, some suggestions about the layout of recharge wells are put forward.
