某新型土工格栅加筋土挡墙的设计方法

施工弃土一般需占用较多的土地,易造成环境污染及资源浪费,若将其作适当工程处理后直接作为构筑物的一部分,综合利用,不仅节省了投资,还有利于环境保护。根据土工格栅加筋土挡墙的加固原理及破坏模式,提出了水运工程中某新型土袋加筋土挡墙结构的设计思路,并对该结构进行了详细的计算分析,特别考虑了浸水条件的特殊性。计算结果表明,此新型挡墙结构安全可靠,对地基的适应性较强,适合在回填土缺少、弃土困难的地区使用。

Design of new-type geogrid reinforced retaining wall

Construction spoil generally occupies a lot of land and leads to environmental pollution and waste of resources, hence the appropriate treatment and application of it as a part of structures not only saves investment, but also is helpful to the environmental protection. Based on geogrid reinforced retaining wall and failure mode of reinforcement theory, we put forward a new idea in the design of reinforced earth retaining wall of water transport project, and carry out a computation of the structure, considering especially the soaking conditions. The results show that the new retaining wall structure is safe, reliable, and suitable for the weak ground and regions lack of backfill.
