The objective of this research project is to develop a low cost sensor array system, based on current state-of-the-art technology of fiber optic and MEMS sensors, for real-time monitoring of ground motion and ground failures such as liquefaction and slope instability through down-hole measurement. It is expected that the new sensor system will be able to measure 3D ground deformation and 2D soil accelerationdown to a depth of 40 meters. Each sensor array will be connected to a wireless node to anble remote sensor configuration.This multidisciplinary team research will be conducted by RPI investigators in collaboration with Caltrans and Army Corp of Engineers.The sensing system would enable a better understanding of ground failure mechanisms and provide an advance sensing tool for geotechnical monitoring. The research outcome will be integrated into the undergraduate curriculum and hands-on sensing module will be introduced to a number of engineering courses.This is a small team project under NSF 03-512.

本研究项目的目标是开发一种低成本的传感器阵列系统，基于当前最先进的光纤和MEMS传感器技术，通过井下测量实时监测地面运动和地面故障，如液化和边坡失稳。预计新的传感器系统将能够测量3D地面变形和2D土壤加速度，深度可达40米。每个传感器阵列将连接到一个无线节点，以便进行远程传感器配置。这项多学科团队研究将由RPI调查人员与加州交通局和陆军工程公司合作进行。传感系统将使人们能够更好地了解地面故障机制，并为岩土工程监测提供先进的传感工具。研究成果将被整合到本科课程中，并将在一些工程课程中引入实际操作的传感模块。这是NSF 03-512下的一个小型团队项目。
