摘要

以龙滩实际工程地下厂房的结构型式为背景，选取对地下洞室围岩稳定性影响较为重要的5个因素，即：岩体变形模量、洞室埋深、主厂房高度、地应力侧压系数以及洞室间距，进行大量的弹塑性数值模拟分析。试图通过回归分析的数学方法，分析围岩关键点位移的变化规律，建立预测模型。并应用预测方法，对在建的和已经完工的实际工程洞室边墙关键点位移进行预测和对比分析，得到较好的一致性效果。

Abstract

Based on the underground structure scheme of Longtan Hydropower Project

lots of elastoplastic numerical analysis were conducted considering modulus of deformation

layout depth of underground opening

height of main power house

coefficient of lateral compressive stress and spacing interval of underground houses as the mainly mechanical parameters that influenced the stability analysis of underground caverns. The mathematical statistics method was employed to investigate the displacement variation law of key point surrounding house periphery and found the forecast model. Then the forecast model was used to analyze the engineerings. It is shown that there is a better agreement between theoretic result and monitoring result in situ[1].
