PC矮塔斜拉桥施工过程主梁内力测试与分析

根据矮塔斜拉桥的受力特点，介绍了梁体关键受力部位测点的布置方案。通过对实测应力值同设计理论值进行的对比分析，研究了该桥施工过程中的主梁受力规律。同时对该桥主梁应力横向分布规律和日照温差对主梁应力的影响规律进行了研究分析。

Test and Analysis of Construction Beam Stress for Wide width PC Extradosed Cable stayed Bridge

In this dissertation, according to the stress characteristics of cable stayed bridge, the test point arranging scheme for the targeted key section of the beam is introduced. By comparing and researching the measured and theoretical value of beam stress, the rule of beam stress during the whole construction is analyzed. The regularity of transverse beam stress distribution and the influence of temperature changing on the beam stress are also analyzed.
