摘　　要：柳城县凤山镇柳江河堤护岸及抢险道路工程需将涉及拆迁路段道路轴线往河岸侧偏移,为了避免道路临河侧侵占亲水护岸用地,并保证河道行洪通畅,需采取占地较少的垂直防护拦挡措施。针对设计路段地层条件较差,不良地层较厚,挡墙段墙体高度最高处达11.6m等实际情况,通过方案比较,选用板桩挡土墙。采用图解法试算、理正岩土软件计算等确定板桩入土深度、挡土墙内力及配筋,进而确定灌注桩及挡板尺寸参数设置。本工程设计充分考虑亲水护岸、抢险道路以及道路设施与镇区景观的结合,有效利用现有空间,合理布局,打造形象鲜明的凤山镇滨水景观工程。The construction of Liujiang River revetment and emergency road project at Fengshan Town of Liucheng County requires the road axis is shifted toward river bank.In order to avoid the riverfront side of the road encroached on the land of water-friendly revetment and to ensure smooth flood discharge in river channels,it is necessary to adopt vertical protective blocking measures with less land occupation.In view of the relatively poor strata condition and fairly thick unfavorable stratum,and the maximum height of retaining wall being 11.6m,based on comparison of schemes,sheet pile retaining wall scheme is selected.The penetration depth of sheet pile and the internal force and reinforcement of retaining wall were calculated by graphical trial calculation and Lizheng geotechnical software,based on which the dimension parameters of cast-in-site piles and baffles were determined.The design of this project fully considers the combination of water-friendly revetment,emergency road and road facilities with the town landscape,effectively makes use of the available space,arranged properly,creates a distinctive waterfront landscape for Fengshan Town.
