施工过程的现场测量是斜拉桥施工监控系统的一个重要组成部分,斜拉桥主梁应力测试属于现场测量的一部分。本文主要对应力测试流程进行了介绍,最后探讨了其测试精度可靠度计算的方法——响应面—蒙特卡罗法,该方法具有精度高、计算量少的特点,是目前一种较理想的结构可靠度分析方法。
The on-site measurement of construction process is an important part of the cable-stayed bridge construction monitoring system. The stress measurement of the main girder of cable-stayed bridge is a part of on-site survey. This paper mainly introduces the stress testing process, and finally discusses the method of the reliability calculation of the test precision - Response Surface - Monte Carlo method. The method has the characteristics of high precision and less calculation, which is a better Structural reliability analysis method.
