Background technology
China's south granite weathering crust mainly is distributed in Guangdong, Fujian, Hunan and the southeast, Guangxi, Jiangxi Gan Nan one band.Because of water erosion, granite weathered crust hilly and mountainous land often forms " white sand hilllock " or " red desert " view.Granite includes 2～10mm, thermal expansion coefficient difference and reaches mineral such as 50% quartz and potassic feldspar, and under the situation of high temperature and rainy, the chemical weathering of Mechanical Crushing is very strong, forms the weathered crust of thick 10～20mm even 50mm.Complete granite weathered crust is made up of soil horizon, red soil floor, sand layer, crumb layer and onion weathering layer.The red clay layer quality on weathered crust top is sticking heavy, and by the iron-aluminium oxide gluing, compares with deep sand layer, the crumb layer in bottom to have stronger erosion-resisting characteristics.When railway passes the granite area, often destroyed the red clay layer on top, sand layer, crumb layer are exposed in the air, caused it to produce serious erosion, erosion intensity is 1.0 * 10
4～1.5 * 10
4T/ (km
2* a), that have even up to 2.0 * 10
5～3.0 * 10
5T/ (km
2* a).Slope wash is corroded has directly increased maintenance of way maintenance cost, the influence operation, and worsen railway periphery ecological environment, and cause adverse consequences such as soil erosion, further develop the generation of the disasters such as landslide that can cause the cut slope avalanche.
