SENSORS: Advanced Sensing for Real-Time Monitoring and Evaluation of Geotechnical Systems

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深度达40米的三维地面变形和二维土壤加速度。每个传感器阵列将连接到一个无线节点，以实现远程传感器配置。这项多学科团队研究将由RPI研究人员与Caltrans和陆军工程兵团合作进行。该传感系统将使人们能够更好地了解地面破坏机制，并为岩土监测提供一种先进的传感工具。研究成果将整合到本科课程中，并将实践传感模块引入到一些工程课程中。这是NSF 03-512下的一个小团队项目。

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.
