A green foundation pit dewatering method

Abstract

The application discloses a kind of green foundation pit dewatering methods, specific steps are as follows: collecting engineering site hydrogeological data, the rock-soil of typical part of engineering site is sampled, and triaxial compression mechanics test under seepage action is carried out to sampling sample;Analysis of the evolution law number of the seepage characteristics and mechanical characteristics of the rock-soil of sampling sample in the process of stress of soil;Constitute the constitutive model of soil elasticity-plasticity under the condition of flow-solid coupling of foundation pit dewatering;Carry out numerical simulation of construction site dewatering;Generate foundation pit dewatering drawing of construction site;Arrange well pipe, carry out engineering application;Carry out dewatering operation, after dewatering engineering ends, well pipe surface is smooth, and well pipe is pulled out for subsequent other dewatering engineering.The application realizes the optimization dewatering scheme method by triaxial test analysis of the evolution law number of seepage characteristics and mechanical characteristics in the process of stress of soil and numerical simulation of dewatering key parameters using Abaqus software, improves information management level and engineering safety factor, is more economical and environmental protection.
