黄土地区路堤病害的主要形式包括路堤或基底沉陷、边坡表面滑溜、路堤局部滑坍和路堤整体滑动等;路堑病害主要产生于边坡,其破坏形式主要有:剥落、冲刷、滑坍、崩坍等。综合分析了黄土的内部构造和环境条件等因素对各种病害的影响,对于路堤,从填料选择、基底处理、边坡设计、防排水措施与路堤压实等关键环节提出了病害防治对策;对于路堑,主要从边坡形式选择、坡度确定、边坡防护加固和加强养护等方面提出了相应对策。
The main forms of embankment diseases in the loess area include embankment or basement subsidence, slippery slope surface, local slump of embankment and overall sliding of embankment. The main road cutting diseases are in slope, and the main failure modes are peel, erosion, slump and collapse Wait. Comprehensive analysis of the loess internal structure and environmental conditions and other factors on the impact of various diseases, for the embankment, from the filler selection, substrate treatment, slope design, drainage and embankment compaction and other key aspects of disease prevention and control measures proposed; for Cutting, mainly from the slope form selection, slope determination, slope protection and strengthening and conservation and other aspects of the proposed countermeasures.
