降雨条件下土工袋对膨胀土边坡加固效果影响试验研究
Experimental Study on the Influence of Soilbags on Slope Reinforcement of Expansive Soil under Rainfall Conditions
摘要
Abstract
Rainfall is one of the main factors inducing the instability of expansive soil slope.To investigate the reinforcement effect of soilbags on expansive soil slopes under rainfall conditions,laboratory physical-scale model tests were conducted on expansive soil slopes with and without soilbags,respectively.The failure time,failure modes,and changes in internal moisture content of the slopes under the two conditions were compared and analyzed.The test results show that the cracks formed on the expansive soil slopes without sandbag reinforcement are mostly deep,and once formed,they spread quickly and cause damage to the slopes in a short period of time;for soilbag-reinforced expansive soil slopes under rainfall conditions,they are mostly surface cracks in the early stage,although the number of the cracks is larger,soilbag reinforcement can effectively inhibit the further development of the cracks,and the time to slope failure is significantly prolonged;in addition,soilbag-expansive soil composites have high permeability,when used for slope reinforcement,they effectively inhibit moisture from infiltrating into the underlying expansive soil slope,providing positive reinforcement performance for expansive soil slopes.关键词
