摘要
介绍路基断面沉降监测常用的几种测试方法和测试原理,并对它们各自的优缺点进行了对比研究,指出采用水平测斜仪监测路基全断面沉降更为有效,它具有不影响施工,不受气候影响、操作方便、精度高等优点,且数据处理简捷方便,结果直观。文中结合具体工程,重点介绍水平测斜仪的工作原理、测试过程和数据处理等内容,并给出测试断面不同时期的沉降曲线和某一次测试的全断面沉降曲线。
The virtues and drawbacks of several general subgrade settlement monitoring methods are presented in this paper. Compared with other methods, the horizontal inclinometer is an efficient method, with advantage of no influence on construction, simply operation, high accuracy and easy for data precessing. Based on practice, the principle, operation rules and the data processing of the horizontal inclinometer are emphasized.
