在基坑开挖过程中,深部土体的水平位移监测是一项十分重要的工作。微机电系统(Microelectro-mechanical Systems,简称MEMS)的概念于上世纪五十年代就被提出,但直到近期才被应用于岩土工程的监测领域。通过室内模型试验,采用由加拿大Measurand公司开发和生产的基于MEMS技术的阵列式位移传感器(Shape Accel Array,简称SAA),可以准确地得到基坑内部陈列式位移传感器(SAA)上任意一点的水平位移。探讨了基于MEMS的准分布式阵列式位移传感器的基本原理,提出了一种基坑水平位移监测的新方法。
During the excavation of foundation pits, horizontal displacement monitoring of deep soils is a very important task. The concept of Microelectro-mechanical Systems (MEMS) was proposed in the 1950s, but it has only recently been applied to the monitoring of geotechnical engineering. Through the indoor model test, the MEMS-based Shape Accel Array (SAA) developed and produced by Measurand of Canada can accurately obtain the level of any point on the SAA. Displacement. The basic principle of the MEMS-based quasi-distributed array displacement sensor is discussed, and a new method for monitoring the horizontal displacement of the foundation pit is proposed.
