摘要近年来建筑业发展迅速，各种类型的工程建筑物越来越多，建筑物的增多，使地面原本的状态遭到改变，而且会对建筑物的地基增加很多压力，这就一定会导致地基和周围的地层变形。为了保证建（构）筑物的安全性和正常的使用年限，以及为后续的监测提供参考，沉降观测是非常重要而且必要的。本文在已有资料的分析利用的基础上，进行沉降监测方案设计的主要内容如下：（1）确定变形监测、监测仪器和水准观测的等级与指标；（2）基准点和基准网的布设，以及基准点的稳定性分析。依据规范要求与相关因素的考虑，快安污水处理厂沉降监测布设3个高程基准点WSC1、WSC2、WSC3。高程基准点的联测采用水准测量方法，使用LEICA　DNA03电子水准仪进行往返测；（3）监测点与监测网网型设计。依据规范及本项目实际情况，在各个构筑物共布设55个沉降监测点WS1～WS55，采用附合水准路线，由WSC1与WSC2组成基准线和WSC3确定附合水准路线两端；（4）沉降观测点的标志与埋设。污水池的沉降观测点采用钢筋观测点标志，处理厂中的建筑物上的标志点，采用角钢或圆钢头观测点标志；（5）水准测量实测方案。基于二等水准观测，采用了单线路往、返观测，并进行精度估算。75802

The Mawei District Kuaian sewage treatment plant subsidence monitoring technology design

Abstract Construction industry has developed rapidly in recent years, more and more various types of engineering structures, buildings, ground originally state was changed, and will increase a lot of pressure on the structure of the foundation, this will lead to deformation of the foundation and the surrounding strata。 Built, in order to guarantee the safety and normal use fixed number of year, and provide reference for subsequent monitoring and settlement observation is very important and necessary。 In this paper, the existing data on the basis of the analysis of the use of settlement monitoring programme design main content is as follows: (1) to determine the deformation monitoring, monitoring instruments and level and index level observation; (2) benchmark and benchmark network layout, and the stability of the datum analysis。 According to the specification requirements and related factors of consideration, fast Ann sewage treatment plant monitoring layout three elevation datum WSC1, WSC2, WSC3。 Elevation datum of measuring the leveling method, using a LEICA DNA03 between measuring electronic level; (3) the monitoring points and monitoring network design。 According to the specification and the project actual situation, 55 settlement were arranged in various structures WS1 ~ WS55, using adhesion level line, composed of WSC1 and WSC2 baseline and WSC3 annexed leveling line ends; (4) a sign of settlement observation point and buried。 Reinforced observation point symbol is used in sewage pool of settlement observation points in the plant building on the landmark, with Angle or round steel head observation point mark; (5) the leveling measurement scheme。 Based on the second level observation, the use of a single line, returned to the observation, and carry on estimation accuracy。
