Study Of Adverse Geological Sections Of Shaanxi And Inner Mongolia Desert Highway Roadbed Construction Technology

This paper regards the ShanMeng desert highway of national road 210 as background, combining with the test in the room and field , promoted the research of systematic summary and test to unfavorable geology section roadbed construction technique of desert highway. The main content is as follows:1. Based on the test of exploring along the highway , analyse the unfavorable geology physics mechanics property , the properties and origin cause of formation of soil. Aimd at the characteristic of unfavorable geology and the demand of top structure required, have proposed the more rational treatment scheme to the unfavorable geology section of highway.2. On the basis of already having materials , analyzed the physical and engineering mechanics property of aeolian sand along the highway.3. On the basis of testing inside and outside the room , summarized the construction compact craft and compact machinery association of aeolian sand roadbed.4. Combine three places to test section, carry on degree of compaction measuring of roadbed, settlement observe of subgrade and superface of roadbed, modulus of resilience of roadbed superface, analysed the rationality of various kinds of treatment methods of unfavorable geology and suitable condition .5. Last , open the discussion into the roadbed subside law of unfavorable geology section in ShanMeng desert highway.
