摘要
在分析国道 30 9线 (宁夏境 )马成河～硝口段地质条件的基础上 ,对沿线灾害地质现象进行了分类 ,认为地貌复杂、岩性破碎 ,尤其是大量发育的滑坡、泥石流和广泛分布的湿陷性黄土是影响公路设计和施工的主要因素 ,并对其所造成的影响进行了评价。
On the basis of analysis of Geologic condition along the national highway 309(NH309) in Ningxia Autonomous Machenghe and Xiaokou Region.This paper analyzs the engineering conditions of the NH309 in Ningxia autonomous region,it concludes that this section of the highway is of the characteristics of complicated geomorphologic and broken rock masses ,as well as a lot of landslides,mud-rock flow and widely distributed collapsible loess and all of these are the main effective factors for its design and construction. Finally there is a evaluateion for the main effecting factor of the engineering geologic condition.
