某连续刚构桥0#块施工裂缝分析

为研究连续刚构桥施工期间在预应力、临时荷载以及温度等耦合作用下的受力特点，保证桥梁施工期间的安全可靠，有必要对该结构进行各种复杂工况下的监控。该文以某连续刚构桥0#块结构为例，运用空间有限元软件对该结构进行了包括三向预应力、挂篮荷载以及温度效应作用下的应力计算，分析了嘴块结构施工裂缝的形成原因，并针对该类型的宽箱结构，提出了相应的设计和施工建议。

Analysis of 0# Block Construction Crack of a Continuous Rigid Framework Bridge

In order to study the bearing characteristics under the coupling actions of the pre-stress, temporary loading and temperature during the construction of the continuous rigid framework bridge, and to guarantee the safety and reliability of the bridge construction period, it is necessary to carry out the monitor of this structure under various complicated working conditions. Taking 0# block structure of a continuous rigid framework bridge as an example, the article applies the space finite element software to...
