皖南山区山体滑坡、泥石流的成因及其防治
- Title:
- The Cause and Prevention of Slideslope, Debris Flow in the Hilly Areas of Southern Anhui Province
- Keywords:
- topography; the intensity of rainfall; slide slope; debris flow
- 摘要:
- 近年来，皖南山区山体滑坡、泥石流发生频繁，给国家和人民生命财产造成巨大损失。通过较为典型的滑坡、泥石流灾害实例调查和区域地理位置、地质构造、地形地貌分析，认为其滑坡、泥石流主要集中在皖南山区东南部的天目山西北翼和绩溪复式背斜的主干山脉。岩层为古生代砂页岩且倾角大于38°的山体，在6～7月梅雨期，24h降雨量超过200mm，什雨强大于30mm时，易产生山体滑坡，局部地区产生泥石流。相应提出了预防和治理措施。
- Abstract:
- In the lastest years, the slideslope and debris occured very frequently in hilly areas of southern Anhui province, which resulted in enormous damage to both the national economy and people’s life and property. Through field investigation on the more typical disaster from slide slope and debris, analysis of geographic position, geologic structure, topography and land forms, we thought that these phenomena are concentratedly distributed in northwestern. Tianmu mountain, southeastern mountain areas in southern Anhui and bakkbone mountain of anticlinorium in Jixi county, which have a grit and cleaving rock stratum belonging to the Palaeozoic, its inclination is greater than 38 degree during plum rainy period in.6~7 month,when the amount of precipitation in 24 hours exceeds 200mm,and the intensity 0f rain in one hour exceeds 30mm,the hillside slip are easily occured, in part of the areas, the debris took place,so we should accordingly put forward some measures to prevent and control them.
