| 摘 要： | 大连港矿石专用码头开挖边坡具有地质条件复杂、边坡较高、开挖土石方巨大、边坡支护难度较高、且边坡易受风化等特点,支护设计与施工工作采取了因地制宜的方针,对于部分稳定坡体进行防护锚杆挂网喷砼支护,局部破碎岩体及风化程度较高的边坡采取了预应力锚索挂网喷砼支护的手段;结合场区整体排水系统,坡顶设置截水沟,坡面设置泄水孔,平台设置截水墙,特殊坡面设置急流槽,坡脚设置排洪沟,并将排水系统与场区内排水终端相连接,边坡绿化经过分析对比,采用适合大连本地区环境的绿化方案;综合各种支护措施,确保大连港矿石专用码头开挖边坡的稳定。

| Abstract: | In the light of the characteristics of the slope-protecting project of Dalian Specialized Ore Quay,i.e.,complicated geological condition,high side slope,great construction quantity of earth rock excavation,difficult supporting of side slope,and easy weathering of side slope,many measures,such as fensing anchor-staffs,prestressed anchor-cables,reinforcing steel bar net spraying cements,and slope virescence,etc.were taken to guarantee the stability of side slope excavation of Dalian Port Specialized Ore Terminal. |
