Study On The Disposal Measures Of Slope Soft Soil Foundaiton Embankment In YUNNAN

Soft soil foundation is a type of foundation is often encountered in the highwayconstruction process, the treatment measures for soft soil foundation in the domestic andforeign is relatively mature. In recent years, found a special type of foundation in thehighway construction in mountainous area of Yunnan, namely the slope soft-soilfoundation, filling embankment on this foundation and prone to instability. Slopesoft-soil foundation and ordinary soft soil foundation is similar, but because the groundsurface has a transverse slope of certain that its engineering characteristics are differentwith the ordinary soft soil foundation. Recently the Second Survey and Design Instituteof the Ministry of Railways in southwest mountain railway construction engineering ofslope soft soil foundation has carried on the related research, in addition, domestic andforeign research on this special foundation data type is rare, especially in the highwayconstruction industry, the relevant specification has not mentioned. Aiming at thissituation, the article on the basis of " the Second Survey and Design Institute of theMinistry of Railways slope soft soil foundation research model" and combining with theTuantian Longteng secondary roads in Yunnan province embankment landslideengineering for further studies on the slope soft-soil foundation filling problem.Firstly, on the basis of " the Second Survey and Design Institute of the Ministryof Railways slope soft soil foundation research model" the artical probe into the effectof hard shell layer thickness on the stability of soft soil foundation slope, think hardcrust thickness should be as the factors influencing the stability of slope soft soilfoundation.Secondly, the artical is studied the influence of hard crust layer existence todeformation characteristics of slope on soft soil foundation, and the existence of hardcrust layer foundation model with " the Second Survey and Design Institute of theMinistry of Railways slope soft soil foundation research model" for comparativeanalysis, found that when the crust layer exists, the slope of the soft soil foundationhorizontal deformation and vertical settlement is relatively small.Then, according to the slope stability and deformation characteristics of soft soilfoundation, proposed the corresponding embankment retaining structure type andfoundation reinforcement measures. Finally, combined with the research results, the Tuantian Longteng secondary roadsin Yunnan province entrance to reinforce dike engineering and treatment effect is good.
