摘要
锚杆格构梁支护体系是利用紧贴坡面的混凝土格构梁和深入坡体的锚杆对坡面进行防护,将护坡与支撑有机结合,结构轻便灵活,施工速度快且支护效果可靠。结合挂网植草,能有效防止边坡冲刷、风化,保证边坡的稳定性。依托宁波—舟山港北仑港区五期集装箱码头竹湾边坡支护工程,详细介绍了锚杆格构梁治理边坡的重点考虑因素、设计方案和边坡绿化,评价了治理效果。结果表明:采用锚杆格构梁支护方案对该边坡进行加固后,边坡在正常工况和暴雨工况条件下的安全系数均明显提高,稳定性增强,边坡安全得到有效保障。
The anchor bolt lattice beam support system uses the concrete lattice beam close to the slope surface and the anchor bolt deep into the slope body to protect the broken surface,organically combines the slope protection and support,with light and flexible structure,fast construction speed and reliable support effect.Combined with hanging net grass planting,it can effectively prevent slope scour and weathering and ensure slope stability.Based on Zhuwan slope support project in the container wharf of Ningbo—Zhoushan Port Beilun Port Area Phase V,the key consideration factors,design scheme and afforestation of slope treatment with anchor bolt lattice beam are introduced in detail and its treatment effect is analyzed.The results show that after the anchor bolt lattice beam support scheme is adopted to strengthen the slope,the safety factor of the slope under normal and rainstorm conditions is significantly improved,the stability is enhanced,and the slope safety is effectively guaranteed.
