| Karakoram Highway which altitudes ranging from 1145 m to 4733 m in Pakistan,passes through Karakorama,Himalayas,and Kush Mountain.Geological hazards are extremely developed,which are caused by natural conditions such as climate,geology,geomorphology,and hydrology.According to the statistics,there are 155 debris flows along the line,114 the collapse and the sliding slope,13 iceberg,7 avalanche and 1 landslides.Based on the analysis of the natural conditions,the use of the China Pakistan highway,the types of geological disasters along the line,the characteristics and the main disaster mechanism of the main geological disasters,this paper makes a comparison of the design standards of the road routes at home and abroad,and puts forward the suitable route for the central Pakistan Karakoram Highway.Standard.In addition,it puts forward the design principles and design schemes to adapt to the general and subgrade design of the highway geological disasters in the middle Pakistan highway,and analyses the disposal principles of the typical geological disasters on the Karakoram Highway through 3 cases of the project selection,the collapse disposal and the glacier debris flow in K677+095.Disposal plan.Through the study of the highway subgrade and the overall technology of the multiple areas of the China-Pakistan highway geological disaster,it can have an important technical support for the construction of the central Pakistan highway,the China Nepal highway and the Middle Tower Road around China,and it will also be the proposed China-Pakistan Karakoram oil pipeline,the central Karakoram railway and the Pakistan N50.The Pakistan N100 highway provides basic information and scientific basis.The demonstration section of the project can also be used as the carrier of China’s international leading road construction level under the extremely difficult conditions to enhance the international competitiveness of China. |
