Abstract

The aim was to design a MATLAB program to calculate the phreatic surface of the multi-well system and present the graphical shape of the water table drawdown induced by water extraction. Dupuit’s assumption is the base for representing the dewatering curve. The program will offer the volume of water to be extracted, the total number of wells, and the spacing between them as well as the expected settlement of soil surrounding the dewatering foundation pit. The dewatering well arrangement is required in execution works, and it needs more attention due to the settlement produced from increasing effective stress.

Highlights

In many places, land subsidence has occurred, especially in heavily populated areas worldwide [1]
The essential objective is to develop an interactive computer-to-user communication software with as little assistance as possible, enabling learning objectives to be met in less time than required. The programming of these programs in Matrix Laboratory (MATLAB) software allows the user to choose from a vast number of parameters related to model programming and design to determine their potential impact on numerical results
The results obtained by the numerical analysis by MATLAB software reflected the site in the example assumed is need to draw down groundwater to 2 m under the foundation, and the parameter site is circumference excavation is 300 m, soil permeability equal 0.0003 cm/second, the thickness of aquifer was 20 m

Summary

Introduction

Land subsidence has occurred, especially in heavily populated areas worldwide [1]. Due to high population intensity, many buildings are adjacent to each other in the same block area These factors increased the propensity to create high-rise buildings. Many of these modern highrise developments are constructed next to existing old buildings. The essential objective is to develop an interactive computer-to-user communication software with as little assistance as possible, enabling learning objectives to be met in less time than required. In this meaning, the programming of these programs in MATLAB software allows the user to choose from a vast number of parameters related to model programming and design to determine their potential impact on numerical results.
