Taizhou Bridge South Anchor Caisson Construction Drainage System Optimization Model of Settlement and Deformation as Constraint Conditions

Abstract

Since construction drainage will inevitably cause ground settlement, it is necessary that a system optimization model is established with source (sink) distribution and intensity being the object function, minimum requirements of settlement and deformation of surroundings caused by draining and dynamic water levels during different working procedures being constraints, and the design parameter of pumping (injection) wells being the variable. The system optimization model solved the problem of which Taizhou bridge south anchor caisson foundation construction drainage induced settlement, so as to lower the damage of surrounding buildings. So the system optimization model provides a new method for active control over settlement during draining. Such a method of drainage based on system optimization model should be of significance for similar projects involving drainage.
