三峡永久船闸衬砌墙结构及结构锚杆受力仿真分析

考虑三维接触非线性的结构采用温度徐变仿真计算方法，针对三峡永久船闸闸一衬式和混合式）的整体和分水平缝两种结构形式，就设计人员关心的温度 、外图生的锚杆应力，结构是分缝，钢筋是否过缝，缝面不同接触条件，锚杆优化等实际问题进行分析比较，结果表明分水平缝可以降低混凝土内应力水平，但部分锚杆应力出现集中现象，钢筋过缝对锚杆应力略有改善，可以在是一步减少锚杆布置。

Simulating Analysis for Forcing of Lined Wall and Anchorage Bars of Permanent Shipping Lock at the Three Gorges Project

Aiming at two types of lock bay wall of unjointed structure and horizontally jointed structure of the Three Gorges permanent shipping lock(whole lined and mixed),some problems concerned by the designers are analyzed and compared with the temperature creep simulating computing method.These problems include anchorage bar stress produced by temperature and outer water pressure,the use of joints reinforcing bars crossing or not crossing joints different contact conditions of crack interface and anchorage bar optimization.The results show that horizontal joints can reduce conrete stresses,but stress concentration may appear in some anchorage bars.Reinforcing bars crossing joints can improve the anchorage bar stress to some extent,so the number of anchorage bars can be reduced.
