摘要
在山区进行工程建设时,时常遇到边坡工程。常见的因填方而形成的边坡高度一般较小,当其高度较大时往往按坡率法采取放斜坡的方式进行支护。该文以重庆某高回填区的一直立边坡为研究对象,分析讨论确定其支护方案采用锚拉式桩板挡墙。通过进一步分析得知土体沉降会对锚杆(索)造成较大的不利影响,并提出解决问题的相应措施。文中对该案例边坡的分析讨论及采取的相关技术措施可供类似工程实践参考之用。最后,对填方边坡支护结构的施工和设计提出一些建议。
Engineering construction in the mountainous area is often confronted with slope engineering.The common slope formed out of backfill generally has a low height,and when the height becomes great the slope ratio method is often adopted to support the slope.Taking a vertical side slope in a high backfill area in Chongqing as the research object,this paper decided to adopt the anchorage pile retaining wall as the supporting scheme after analysis and discussion.Through further analysis,it is found that the soil settlement will cause great adverse effects on the rod(cable),and the corresponding measures to solve the problem are presented.The analysis and discussion of this sample slope and the relevant technical measures taken in this paper can be used as reference for similar engineering practice.Finally,some suggestions are proposed for the construction and design of the support structure of the fill slope.
