襄荆高速公路膨胀土堑坡开挖及防护的变形监测与分析

DEFORMATION MONITORING AND ANALYSIS ON EXPANSIVE SOIL SLOPE DURING CUTTING AND PROTECTING IN XIANGJING EXPRESSWAY

摘要: 对襄荆高速公路膨胀土试验段堑坡开挖和防护全过程进行了变形监测。通过对比研究边坡在不同干湿循环条件、不同阶段的变形特征,探讨了减少边坡变形的关键影响因素,分析了挡土墙与坡面防护的作用,提出了合理的开挖与防护建议。

Abstract: A deformation monitoring on expansive soil slope during cutting and protection was completed in Xiangjing Expressway. Based on contrast research on deformation characteristics of slope in variant weather condition, cutting and protection situation, the crucial factor was discussed to diminish deformation; the function of retaining wall and surface protection was analyzed; then some corresponding advice was given for cutting and protection of slope.
