[Abstract]:Loess region in northern Shaanxi Province is characterized by special landform, geology and climate conditions. It is a frequent area of highway water destruction, which brings huge economic losses every year because of highway water damage. The establishment of a sound and reasonable subgrade drainage system can effectively reduce the occurrence of highway water damage, because of various reasons, the existing subgrade drainage system has many unreasonable points, which can not fully meet the requirements of regional drainage. Therefore, the study on drainage technology of trunk highway in loess region of northern Shaanxi province can improve the rationality of subgrade drainage system, promote the function of subgrade drainage system, reduce the damage of highway in the region, and prolong the service life of road. It is of great significance. On the basis of summing up the research of highway drainage technology at home and abroad, the geological and environmental conditions, climatic conditions and their effects on subgrade drainage system in loess region of northern Shaanxi are summarized and analyzed through consulting data and field investigation. Based on the subgrade drainage system of S302S206G307 in Yulin, Shaanxi Province, this paper has carried out field investigation and summarized the problems existing in the drainage facilities such as edge ditch, jet channel, intercepting ditch, culvert and so on, and analyzed its causes. Based on the theory of fuzzy mathematics, the evaluation model of subgrade drainage system is established, and the rationality of the model is verified by an example. On the basis of the above research, combined with the characteristics of loess region in northern Shaanxi and the theory of drainage design, the principles, steps, contents and main points of drainage design suitable for loess region in northern Shaanxi are summarized. It can provide technical guidance for drainage design in loess region of northern Shaanxi. The method of drainage standardization design is put forward, and the dimension table of slope drainage facilities in loess region of northern Shaanxi is calculated. When the runoff length and catchment area are known, the dimensions of drainage facilities can be obtained by checking the size tables. It greatly reduces the randomness and workload of slope drainage design. Based on the importance of highway drainage in loess region of northern Shaanxi, the subgrade drainage system in loess area of northern Shaanxi should pay attention to data collection, change design ideas and control quality in construction stage. The measures of promoting the function of subgrade drainage system and reducing the disease of subgrade drainage system are discussed in detail.
