The invention belongs to the technical field of slope engineering, and particularly relates to a protective structure of an expansive soil cut slope and a construction method of the protective structure. The invention provides a protection structure of an expansive soil cut slope. The slope surface and the slope top of a slope comprise a slope crack treatment layer, a two-cloth one-film layer and a vegetation protection layer which are sequentially arranged in a stacked mode. The drainage ditch is arranged at the toe of the side slope; the intercepting ditch is arranged on the outer side of the slope crest protection structure; the side slope crack treatment layer comprises a side slope surface with cracks, a slope top and an emulsified asphalt composite material filled in the cracks; the vegetation protection layer comprises a backfill cultivation soil layer arranged on the surface of the two-cloth-one-film layer and vegetation arranged on the cultivation soil layer. The emulsified asphalt composite material has good fluidity, and permeates into the cracks to enable the cracked expansive soil slope to be compactly filled into a whole. The vegetation protection layer and the two-cloth-one-film layer can well prevent external moisture from permeating into the slope body, meanwhile, evaporation of moisture of the slope body can be reduced, and the stability of the slope is effectively maintained.
本发明属于边坡工程技术领域，具体涉及一种膨胀土堑坡的防护结构及其施工方法。本发明提供的膨胀土堑坡的防护结构，边坡的坡面和坡顶位置包括依次层叠设置的边坡裂隙处理层、两布一膜层和植被防护层；设置于边坡坡脚处的排水沟；设置于边坡坡顶防护结构外侧的截水沟；所述边坡裂隙处理层包括带有裂隙的边坡坡面、坡顶和填充在裂隙中的乳化沥青复合材料；所述植被防护层包括设置于两布一膜层表面的回填耕植土层和设置于耕植土层之上的植被。乳化沥青复合材料具有良好的流动性，渗入裂隙中使开裂后的膨胀土边坡填充密实成为整体。植被防护层和两布一膜层能很好地防止外界水分渗入坡体内部同时也能减少坡体水分的蒸发，有效维持边坡稳定性。
