摘要
地基基础计算及稳定性分析模块是重大工程地下环境信息系统的重要模块之一,是以工程地质勘探及设计施工资料为基础,以地理信息系统为开发平台,结合数据库技术、面向对象编程技术、信息技术等先进技术建立的。利用此模块对重大工程中桩基设计、复合地基设计、洞室围岩设计数据进行存储及查询,并依据相关行业规范建立分析模型,对桩基、复合地基、洞室进行设计计算,并进行边坡稳定性问题分析。本文阐述了此模块的功能特点与实现方法,并对空间数据搜寻、单桩截面水平位移及弯矩计算、边坡稳定性分析等关键问题及其解决方法作了介绍,最后对本模块在东深供水改造工程中的应用效果作了描述。
As an important module of underground environment information system in major project,soil-foundation calculation and stability analysis module is building on database management technology,object-oriented programming and information technology,which is based on the information of prospecting and construction.It takes GIS as its workstation.The design information of pile foundation,composite grounds,tunnel and side slope can be stored and be edited by this module.Conform to the relative technical code in geotechnical engineering,some analysis models is created to make pile foundation design,composite foundation design,tunnel design and stability analysis of side slope.The functions and the realization methods of this module are introduced and key questions,including space data inquiry,calculating the displacement and moment of single pile section and stability analysis of side slope, and the solutions are discussed in this paper.At the end of the paper,it is described that the effects of applyingthis module in Dong-shen water supply improvement project which is the biggest water conservancy recent years.
