摘要

为了保证溪洛渡水电站地下厂房岩锚梁的结构安全，研究进一步采取综合温控措施防裂的有效性和合理性，通过对地下厂房岩壁吊车梁在春季和夏季施工进行三维仿真分析，得到温度场和应力场的分布及其随时间的变化规律并进行分析比较，同时分析了春夏两季裂缝产生的不同原因，为以后的裂缝处理提供了参考依据。

Abstract

In order to ensure the structure safety on the anchored beam of Xiluodu Hydropower Station

and to study the effectiveness and reasonableness of comprehensive temperature measures to prevent cracking

a 3-D finite-element analysis is used to simulate the construction process and the temperature control measures. Based on analyzing the distritutions of thermal field

stress field and their variation laws are compared each other. The results of the temperature control in initial stage has important engineering significance for construction.
