青藏铁路无人值守地应力综合监测站

介绍了安装在青藏铁路沿线一种新型的无人值守综合地应力监测站。该监测站采用无线GPRS通信技术,通过Internet连接到安装在北京的地质力学研究所地应力监测局域网中心端服务器,实现数据交换和监测站的远程控制,该项技术克服了传统地应力测量需要人工现场信息采集的弱点,使用数据终端来实现地应力监测的自动化。该监测站能够进行青藏铁路沿线的昆仑山、安多、羊八井深孔应力监测和昆仑山西大滩昆中断裂位移监测,可以对青藏铁路沿线地球物理数据、地质灾害数据、地质环境数据及地球动力学过程实现不间断的监测,为青藏铁路沿线的地质灾害、青藏高原构造变形动力学过程的研究和地震预报、高原环境研究提供基础数据,增强了对青藏高原地质灾害、地震的预警能力。 

UNMANNED IN-SITU STRESS MONITORING STATIONS ALONG THE QINGHAI-TIBET RAILWAY

The paper introduces a new type of unmanned automatic in-situ stress monitoring station installed along the Qinghai-Tibet Railway. By using the wireless GPRS communication technology, the station is linked through internet to the central server located in the LAN for in situ stress monitoring in the Institute of Geomechanics, Beijing to achieve data exchange and telecontrol by the monitoring stations. This network overcomes the shortcoming of conventional in-situ measurements needing artificial in-situ information collection and uses the data terminal to realize the automation of stress monitoring. The monitoring stations can monitor deep-hole stresses in the Kunlun Mountains, Amdo and Yangbajain along the Qinghai-Tibet Railway and displacements of the Central Kunlun fault at Xidatan, Kunlun Mountains. Through continuous monitoring of the geophysical, geological disaster and geo-environmental data and geodynamic process along the Qinghai-Tibet Railway, the stations can offer basic data for the study of geological disasters occurring along the railway and tectonic deformation dynamic process of the Qinghai-Tibet Plateau, the early-warning ability earthquake forecast and plateau environment. Additionally, they can enhance for geological disasters and earthquakes on the Qinghai-Tibet Plateau.
