Soft earth passenger special line embankment and supporting design
Abstract: in recent years, along with the rapid development of economy, science and technology level of rapid ascension, increasingly frequent guest designed roadbed engineering construction in China, met a lot of bad roadbed, and most of the soft soil, and to collect the engineering properties of soft soil and hydrogeological condition such as data packing for soft soil improvement and measures to deal with soft soil subgrade correspondingly. Of this course is designed for traffic engineering professional graduation design, its content is mainly based on the given engineering geological and hydrological conditions such as soft soil foundation, embankment and supporting design, mainly includes the following contents: 1. The road embankment design of passenger dedicated line 2 and embankment slope stability calculation of embankment slope supporting design.3. Design the slope protection plan.
Key words: graduation design; Soft soil; Embankment; Support; Slope protection
