摘要
小湾拱坝动静应力水平较高,在拱坝体型优化及应力分析中采用多种数值分析方法和模型试验进行深入研究,特别是对于高拱坝坝踵可能出现的开裂问题和抗震问题开展了一系列攻关研究,并采取了相应的工程措施。坝肩稳定是高拱坝安全的关键,针对存在于坝肩抗力岩体内的地质缺陷,首先采用多种数值分析方法和模型试验对抗滑稳定性和变形稳定性进行深入研究。在此基础上,从安全可靠、经济合理以及可实施性等方面充分论证和分析比较各种加固处理措施,综合确定了实施方案。
The Xiaowan arch dam has big dynamic and static stresses. Many numerical analysis methods and model tests have been used to the analysis of arch dam type optimization and dam body stresses. A series of key studies have been made in the possible cracking and anti-quake problems in the high arch dam and some engineering have been taken. The stability of dam abutment is the key to the safety of high arch dam. In accordance with the geological defects in the rock bodies of dam abutment, many numerical analysis methods and model tests have been used to deeply study the stability against slide and the deformation stability. And then the aspects of safety, reliability, economic reasonability and practical application have been verified fully and analyzed to select the reinforcement treatment alternatives. Finally the implementation scheme has been determined.
