Abstract


Climate and other reasons , the province has built a high-grade highway roadbed slope often hillslope erosion , shallow slump , protection works damaged , slipped , and other diseases , not only directly affect the overall highway use and environmental coordination , but also greatly increase post maintenance , the difficulty and cost of maintenance . With other parts of the country due to the limitations of the geographical and economic conditions for the development of lack relevant research generally , lack of protection technology based on the lack of regional the typical protection mode , plant species selection and cutting slope gradient determine randomness and other issues still exist. The investigation summary , the province high-grade highway soil the roadbed slope protection type , the use of the status quo , analysis of the the Slope disease manifestations and its influencing factors , systematic observation and laboratory and field test on the basis of soil subgrade slope frozen thaw slumping damage critical gradient for erosion , in-depth analysis . Pointed out that the mode of action of each factor of the freeze-thaw slumping , confirmed the key influencing factor is not the slope , but the shear strength in the the common embankment slope range ( 1:1 to 1:2 ) , the slope of freeze-thaw slumping . Within the embankment slope , slow down a slope can not avoid the freezing and thawing of the occurrence of slumping , the analysis showed that the slope masonry additional load have a significant impact on the slope slumping stability . Freeze-thaw slumping stability checking formula , the formula can be used for the quantitative analysis of the various factors to determine . Rainfall intensity of different natural divisions of the province divided mechanics critical gradient for erosion on the slope 1:1 slope is the critical gradient range , affected by the rain washed serious , should be to avoid or strengthen the scour protection design and test the the recommended protective type and construction technology .
