摘要
本论文提出一种基于激光测距原理的非接触式滑坡表面裂缝监测方案,该智能化监测方案利用GPRS方式进行数据的远程传输,解决了现有的电磁式、接触式地表裂缝计存在容易被损坏、易受干扰及测量误差大的技术问题,同时也解决了GPS或是全站仪存在成本较高、计算和安装复杂、实时性较差等技术问题,实现了在低成本条件下的滑坡表面裂缝实时监测,并在四川省巴中市典型滑坡点上进行野外应用示范,取得了良好的监测预警效果,为地质灾害防灾减灾提供技术支持。
The paper proposes a non-contact landslide surface fissure monitoring design based on laser ranging principle. This intelligent monitoring design uses GPRS to transmit data and this design will solve these technical problems such as vulnerable, disturbed and measurement errors, which exist in electromagnetic and contact-type landslide fissure monitors, meanwhile it also solve problems such as high cost, installation complexity and low real-time in GPS or total station. This method realizes real-time landslide monitoring with low cost, and it has been carded out field test on landslide in Bazhong City, Sichuan Province. With the great effect in landslide monitoring, this system will provide technical support in geological disaster prevention and reduction.
