软弱土地区城市道路河道生态护岸设计

南充市顺庆区荆溪河沿岸滨河路及护岸建设过程中，大部分河段存在较厚的软塑粉质黏土。该层土物理力学性质较差，对道路建设和护岸稳定极为不利。滨河路是拟建的休闲景观大道，因此该工程在保证道路和护岸安全的前提下，提出生态需求。根据场地工程地质情况，选取了斜坡式生态护岸形式，即表面采用绿化混凝土护坡与客土绿化，坡脚采用格宾石笼护脚，针对较厚的软塑粉质黏土区域采取水泥土搅拌桩进行加固处理。监测结果表明护岸方案整体稳定性及不均匀沉降满足要求。

Design of Ecological Revetment for Urban Road Rivers in Soft Soil Regions

During the construction process of Binhe Road and revetment along the Jingxi River in Shunqing District, Nanchong City, there is the thick soft plastic silty clay in the most sections of the river, which has the poor physical and mechanical properties and is extremely unfavorable for the road construction and revetment stability. Binhe Road is a proposed leisure landscape avenue. Therefore, under the premise of guaranteeing the safety of road and revetment in the project, the ecological needs are proposed. Based on the engineering geological conditions of the site, a slope-type ecological revetment form is selected, which uses the green concrete revetment and guest soil greening on the surface, and the gabion slope protection at the foot of the slope. Aiming at the thick soft plastic silty clay area, the cement soil mixing piles is used to carry out the reinforcing treatment. The monitoring results indicate that the overall stability and uneven settlement of the revetment scheme meet the requirements.
