摘要
某市河道边坡因常年缺失治理,边坡存在失稳隐患,为防止损害人民的生命财产安全,对河岸的边坡进行支护治理.采用挡土墙与木桩结合的支护方案对边坡进行支护,木桩紧密排列,截面为实心圆形.通过采用Midas对支护的边坡进行稳定性分析,利用GeoStudio软件采用强度折减法计算了支护边坡的安全系数,对比两种支护方案的稳定性与造价.虽然两个方案都满足要求,但木桩在挡土墙右侧2.6 m处进行支护的方案,边坡支护更具稳定性,造价也比较低,且满足规范要求.因此选择的方案来进行支护河道的边坡.
Abstract
Lacking of management all year round,slopes of rivers in cities are at risk of instability.In order to pre-vent damage to people's lives and property,the slopes are supported and managed by combining retaining walls and wooden piles,where the wooden piles are closely arranged and have a solid circular cross-section.Midas is used to conduct stability analysis of the supported slope,and GeoStudio software is used to calculate the safety factor of the supported slope using the strength reduction method,and the stability and cost of the two support schemes are com-pared.Although both solutions meet the requirements,the solution in which wooden piles are supported 2.6 m to the right of the retaining wall provides more stable slope support,lower cost,and meets the specification requirements.Therefore,the solution is chosen to support the slope of the river channel.
