摘　　要：在对边坡进行植被混凝土护坡时,施工过程中经常出现降雨造成种植土含水率过高,使得混合料中颗粒团聚增大,黏度增加,出现堵管现象,影响施工正常进行。分析了颗粒团聚及堵管的原因,并通过掺入碎石,研究了碎石掺量对过湿植被混凝土性能的影响,研究结果表明,碎石掺量对不同含水率土壤混合成的植被混凝土的影响机理不同,土壤含水率较低时,碎石掺入后能较好解决颗粒团聚和堵管现象,且对植被混凝土性能影响不大,当土壤含水率过高时,能够降低堵管发生的次数。During the slope greening,the rains often cause the moisture content of soil elevated. It makes the size and viscosity of agglomerated particle increasing,and the pipeline jamming. It has affected the normal construction. The article analyzed the reasons of agglomerated particle and pipeline jamming,then researched deeply the influence of gravel content for the slope protection efficiency with super-humid vegetation growing concrete by joining the rubble. The results showed that gravel content on the influence of different moisture content of vegetation concrete is different. When the moisture content is low,the gravel can solve the agglomerated particle and pipeline jamming,and don ＇t affect the strength of vegetation concrete. When the moisture content is high,the gravel can reduce the number of pipeline jamming.
