| 摘 要： | 大量现场调查和观测发现,川藏公路四川段的泥石流灾害集中分布在4个区域,即龙胆溪泥石流区、雅江泥石流区、波戈溪泥石流区和巴塘—金沙江泥石流区。波戈溪泥石流区和巴塘—金沙江泥石流区是境内泥石流灾害最严重的地区,流域面积超过20 km~2的特大型泥石流有24条。自东向西,川藏公路四川段泥石流由水石流逐渐演变为稀性泥石流;复杂的地质构造环境、高山深谷地貌特征、强烈的地震活动、高强度的降雨和冰雪融水,构成泥石流灾害显著发育的环境条件。将公路沿线泥石流形成机理概括为4种,即降雨冲击机理、强度衰减机理、冲刷切割机理和沟床拖拽机理;2003年以来采用护岸结构、速流结构、抗冲击结构、拦渣坝、消能坎等技术实施了30余个大型泥石流灾害治理工程,治理效果显著。 |

| Abstract: | Large numbers of field investigation and observation have revealed the distribution regularity of debris flow disaster along the Sichuan-Tibet highway in Sichuan province,which consists of four zones respectively in Longdanxi catchment,in Yajiang catchment,in Bogexi catchment and in Batang-Jinshajiang catchment.Specially,debris flow disasers are deeply serious in both Bogexi and Batang-Jinshajiang catchments, there are 24 giant debris flows with their basin areas over 20 km~2.From east to west along the hig... |
