摘要
斜拉桥钢-混组合索塔锚固区构造和受力十分复杂,通过索塔锚固区的足尺模型试验,并进行空间的有限元仿真计算分析,给出仿真计算的主要成果及其与试验实测值的比较,得出一些重要结论。试验成果对杭州湾跨海大桥的建设起到了重要的指导作用。
The structure and mechanical conditions of the steel and concrete composite anchor zone on pylon of cable-stayed bridge are extremely complicated. In the is paper, based on the fullscale model tests for the steel and concrete composite anchor zone on the pylon, and simulation calculation and analysis with spatial finite element method, the principal results of the simulation calculation, comparison of the results to the measurement values in the tests are provided, and some important conclusions in relation to the calculation and tests are generalized. The results of the tests are of important guidance to the construction of Hangzhou Bay Sea-Crossing Bridge.
