Abstract


The Loess region has special topography , geomorphology , geology and hydrology climatic conditions , is one of the areas of the western region the most severely damaged roads , the annual flood season road loss of water-related disasters serious , severely restricted the areas of highway construction and economic development . The heavy rainfall caused flood the loess areas damaged roads and the main causal factors , and many damaged type based on the damage to the drainage , failure as early disaster development characteristics of scientific and rational set of highway drainage facilities , improve drainage systems, to improve their disaster resilience necessary measures to reduce the damaged roads . But due to various reasons , the existing drainage structures in terms of type, material , and disaster resilience , can not completely meet the loess highway waterproofing and drainage requirements , research loess areas and damaged roads , propose suitable new drainage patterns , has important engineering significance. This paper analyzes the loess highway drainage prevention natural environmental conditions through the usage and water damage on the highway drainage system on-site investigation , combined with over the years Washout data analysis on the the Loess highway drainage systems damaged by water type classification and further analysis produce water damage . On this basis , the domestic and international data analyzed and summarized the new highway drainage type with new material proposed approach for the import and export of rapids slot and slot itself ; through comparative analysis of precast concrete panels ditches tube Rapids slot characteristics of the applicable conditions and construction points ; several new materials and conditions of use of the drainage system . Also for the climatic conditions of the characteristics of loess slope and loess region proposed for the region of Loess Slope form of plant protection . Combination of natural and geographical conditions , the Loess region suitable for new highway drainage type and layout conditions , to choose typical test sections in Yulin loess , a new type of drainage facilities , through regular observations and data analysis , and its use of effects analysis and evaluation . The results proved that the new type of drainage facilities with strong applicability and anti destroyed the ability to promote the use of in the loess region .
