混凝土坝空间位移场监测模型的探讨及应用

Monitoring Model of Space Displacement Field of Concrete Dam and Its Application

该文从场论出发,应用幂级数的处理方法,并结合坝工理论和工程力学知识,全面论述了建立混凝土坝空间位移场的动态监测模型的基本原理和计算公式,并将其应用于建立丹江口左岸转弯坝段34#、36#坝段正垂线的分布模型,通过对模型成果较为深入地比较和研究,得出此模型是一种很好的变形监测模型的结论,在全面监测大坝工作情况时,其发挥的作用是单个测点变形模型不可比拟的,尤其是和单个测点的监测模型联合,从点、线、面全面监视大坝工作情况,更能充分发挥各自优越性.

Based on the field theory, this article discusses basic principles and calculation methods for establishing dynamic monitoring models of the space displacement field in a concrete dam, the application of power progression, and combination of the dam theory with engineering mechanics. The monitoring model is applied to establish a distribution model of the leftmiddle vertical line of the dam sections Nos.34 and 36, which are parts of the turning dam sections on the west bank of the mouth of Dan River. By comparison, it is concluded that the model is suitable for deformation monitoring. In overall monitoring of the dam, it is better than the single point deformation model. When combined, the two models can show their respective advantages in monitoring the dam's work from point, line to plain.
