摘要

在水电工程中，河谷两遍的工程边坡具有尺度大、高而陡的特点。同时这些边坡服务年限长，稳定性要求高。对于耦合考虑施工进度和工程安全的动态分析还较少涉及。由于地质参数、边坡结构和开挖支护的实时变化，对边坡工程安全的实时评价已成为制约水利水电工程建设安全的关键技术问题。考虑边坡施工过程中开挖进度的调整、新地质信息的揭露、支护方案的修改及计算参数的修正等信息实时变化的客观实际，重点针对目前较少涉及的施工期高边坡工程安全的实时分析和控制问题，提出了基于数值模拟技术的边坡实时安全仿真方法；基于数据库技术和ABAQUS二次开发技术实现施工进度信息、地质信息及支护信息到数值计算模型的动态映射，开发了边坡安全实时分析系统，最终实现了与施工进程相适应的边坡安全状态实时仿真分析和预测。

Abstract

In hydropower engineering

engineering slopes on both river sides have characteristics of large scale

high and steep geometry

long service life and high stabilization requirement. Due to real-time changes of geological parameters

slope structure and excavation support

real-time evaluation of slope safety is a key technical issue in hydropower projects. A real-time simulation method based on numerical method is developed by considering the change of excavation progress during slope construction process

the new geological information disclosure

the modification of supporting plans and the correction of numerical parameters. This procedure focuses on real-time analysis and control of the safety of high-steep slopes

which is seldom reported in the previous studies. Based on database technology and secondary development of ABAQUS software

the information of dynamic mapping the construction schedule

geology and support is implemented into the numerical model. Finally

a real-time analysis and control system for slope safety is developed to realize the simulation and forecast of the real-time slope safety status.
