中文摘要:
      极端天气条件下,滑坡灾害发生频次更高、影响范围更广、社会影响更大。监测预警是减缓地质灾害风险有效措施之一。降雨是影响边坡稳定性的重要因素,降雨型滑坡安全预警系统的研究方面取得了不少成果。本文对适用于不同岩土类型的滑坡安全预警模型进行分类总结,对未来的研究工作具有一定的指导作用。对研究成果进行归纳分析发现:滑坡安全预警模型逐渐转向对特殊岩土类型边坡的研究;比例尺较大的县乡级的区域降雨滑坡预警更适合我国的国情;目前降雨型滑坡模拟物理试验及数值模拟试验研究仍显不足,降雨型滑坡安全预警模型在实际预警工作中还存在误差。为提高坡体滑坡监测和安全预警效果,未来应大力开展基于卫星遥控遥测技术的滑坡监测与预警预报系统研发利用,加强对各影响边坡稳定性因素的相互作用研究。
英文摘要:
      Landslide disasters occur more frequently, have a wider range of influence and a larger social impact under the conditions of today’s extreme weather. Monitoring and early-warning is one of the effective measures to mitigate the risk of geological disasters. Rainfall is an important factor affecting the stability of the slope, and many achievements have been made in the research of safe early-warning system for rainfall-induced landslide. This paper classifies and summarizes the safe early-warning models of landslide suitable for different types of rock and soil, which has certain guiding role for future research work. We found that by summarizing and analyzing the research results: the safe early-warning model of landslide gradually turns to the study on slopes of special types of rock and soil; the early-warning of slope at county and township level with large plotting scale is more suitable for China"s national conditions; at present, there are still some deficiencies in the study of simulated physical test and numerical simulation test of rainfall-induced landslide, and there are still errors in the practical early-warning work of safe early-warning model for rainfall-induced landslide. In order to improve the effect of monitoring and safe early-warning for slope landslide, the research and development of monitoring and early- warning system for landslide based on satellite remote control and telemetry technology should be vigorously carried out in the future, and the study on interaction of each factors affecting slope stability should be strengthened.
