由于基坑支护系统通常为临时设施,而且工作状态和条件比较复杂,不确定因素很多,考虑应急措施是非常重要的。所以,在支护系统中,支护状态的动态监测与控制是一个不容忽视的重要环节。监测的内容一般包括基坑土体的位移,支护结构的变形与内力,地下水位的变化,坑周建筑物与构筑物沉降、倾斜、开裂及工作状况等。总之,在深基坑开挖施工时,基坑支护绝对不能忽视,否则必然会造成较大的损失。
As the foundation pit support system is usually a temporary facility, and the working conditions and conditions are complex, with many uncertainties, it is very important to consider the emergency measures. Therefore, in the support system, the dynamic monitoring and control of support status is an important part that can not be ignored. The monitoring contents generally include the displacement of foundation soil, the deformation and internal forces of support structure, the variation of groundwater level, the settlement, inclination, cracking and working conditions of plinth buildings and structures. In short, when deep excavation construction, foundation pit support absolutely can not be ignored, otherwise it will inevitably cause greater losses.
