TXP非线性有限元程序系铁道部科学研究院西南所编制的,用于分析隧道围岩稳定性及支护系统静力工作条件。针对隧道工程中所遇到的坚硬、层状及软弱等各种围岩条件,该程序分别考虑了不同的岩体破坏形态及岩体破坏所引起的应力—应变关系的非线性特点。经在几个铁路隧道及其他地下工程中试算和使用,取得较好效果,为隧道工程围岩稳定分析和支护系统的设计提供了一个有效的工具。审查会于年前12月中旬由铁科院在峨眉召开。会议首先由编制单位介绍TXP程序的功能和使用情况,
TXP nonlinear finite element program is compiled by the Southwest Research Institute of Science and Technology of the Ministry of Railways for analyzing the stability of tunnel surrounding rock and supporting system static working conditions. In view of the various surrounding rock conditions such as hard, stratified and weakness encountered in tunnel engineering, this program separately considers the nonlinear characteristics of stress-strain relationship caused by different rock mass failure modes and rock mass failure. After several trials and applications in railway tunnels and other underground works, good results have been obtained, which provides an effective tool for the stability analysis and support system design of surrounding rock of tunnel engineering. The review meeting was held in Emei by the ASTRI in mid-December of the previous year. Meeting first introduced by the preparation unit TXP program function and usage,
