A Research On Soil And Water Conservation For Expressway

In the past ten years, many developments happened in expressway constructing fields. The expressway network has great effect on environments in despite of its society & economic benefits.There have been many researches on the relationships between expressway and Environment from inland and abroad, however, how to deal with soil and water conservation needs much attention especially for plain. There is much more attention on soil and water conservation along with environment labefaction in recent years, and that is a basic policy in our country. Roadway constructing destroys the earth's surface structure and vegetation against soil and water conservation. Strongly safeguards must be taken during roadbed filling soil and dust getting. Some expressways' construction plan must develop unattached research report on soil and water conservation according to state rules. The thesis topic is expressway construction to take into account soil and water conservation. Consequently this thesis topic has much significance to soil and water conversation on expressway of plain. The value of engineering applications is obvious.The actuality and shortage on overseas expressway soil and water conservation is an important research task in the thesis. The author presents a new design standpoint basing on giving priority to prevent and relating main project after analyzing how to compile report about soil and water conservation. In allusion to plain Lakeland in Jiangsu Province, it discusses some problems and countermeasures in the course of survey and forecast on soil and water disappeared. At the same time, the author researches the forecast theoretic and design flow emphasis on low roadbed and optimizing use scrap soil against prevention and cure of project. Innovative design way on collectivity idea has great practicality, and it is the soul part of the thesis. The way to write soil and water conservation report of the thesis has much reference value to plain Lakeland area on soil and water conservation.
