Research On The Soft Foundation Supervisal And Settlement Of Freeway In Western Mountains Areas

In western China, there is a lot of hills and mountains, are located along the freeway with a large number of high embankment. In the mountain valley areas, but also the distribution of Embankment on Soft Foundation. The fill section stability and long-term settlement of the situation during the operation of a major impact on the freeway, soft foundation became the key factor of the project.Mountain freeway construction, inevitably encounter soft foundation, there are many successful examples, but there are also failures. The construction of freeway through the years, summed up the experience of a more important:For the more complex geological problems, must be in engineering construction, strengthen the construction monitoring, construction monitoring through, reflect the actual project, engineering geological characteristics and changes in the feedback, and thereby play a guiding construction, control construction, security engineering security. Therefore, to make soft embankment stability monitoring and construction monitoring technique is very necessary.Paper into the South Freeway through the high embankment, high bridge embankment and key sections of Embankment on Soft Ground subsidence monitoring technology and settlement after the summary and analysis of observational data to improve the settlement after the occurrence of the development of understanding of the law. Paper into the South on the basis of long-term follow-up observations, analyzes and summarizes the soft mountain valley phase monitoring rules. Summed up the mountain valley settlement after the phase of some ground rules.Paper with a large number of observational data to improve the foundation of the mountain valley settlement after the phase prediction method, and conducted regression analysis to study the deformation of soft embankment rate control standards, uneven settlement of the relevant control standards were derived, reached a certain conclusion, for the project construction quality control of certain reference standards.
