长山堡特大桥悬浇梁施工监控

Construction Supervision of Changshanbao Ultra-size Suspension Cast-in Situ Beam

公路悬浇梁施工监控就是控制施工过程中和成桥状态时结构的内力和线形,以使悬浇梁的成桥状态充分满足设计要求。本文以辽宁省草市至南杂木高速公路长山堡特大桥工程施工监控为背景,介绍了施工监控的过程,实现两个主要目的,一是在施工完成时使结构达到设计的几何线形,二是在完工后使结构达到合理的内力状态,同时保证结构在施工过程中的安全。

Suspension Cast-in Situ Beam construction is to control the construction process and bridge state of internal force and linear, so that the bridge State could fully meet the design requirements. In this paper, taking the ground of Changshanbao ultra-large Suspension Cast-in Situ Beam in Grass City, Liaoning Province, the process of construction monitoring is introduced which achieves two main purposes, first, the construction is completed to meet the design of the geometric structure of linear, Second, after completion, make he structure into a reasonable state of internal forces, while ensuring the structural safety of the construction process.
