摘要
针对因膨胀土胀缩性而引发的航道护岸变形问题,研究处理措施。将"多级放坡+浅层改性换填+表层隔排水+深层桩基"组合型护岸结构应用于某航道工程,达到无变形、无裂缝的工程效果,验证了该种组合结构措施抵抗膨胀土胀缩的能力,适用于有桥梁等交叉建筑物的重点航段。
To counter the problem of channel revetment deformation due to swell-shrinking of expansive soil,we probe into the countermeasures.Appling a combined revetment structure,i.e.,multi-grade slope+backfill of improved soil+surface water drainage+pile foundation,to a channel engineering,we achieve the engineering effect of no deformation and no crack.It proves that such combined structure does resist swell-shrinking of expansive soil and is suitable for the key channel part with bridge or other crossing structures.
