摘　　要：采用六边形双绞合金属网面,经工厂化生产形成面墙,面墙与金属网面无接点整体连接形成一种新的加筋结构—加筋格宾结构,目前国内工程应用较少,相应的计算理论与设计方法滞后,难以满足工程需要。研究表明,双绞合钢丝网加筋格宾挡土墙比传统的条带式加筋、土工格栅挡土墙的稳定性好得多,适合于修筑高大及高等级公路的挡土墙。在吸收国外先进加筋技术的基础上,通过拉伸、拉拔试验合理确定了相关设计参数,采用室内大型模型试验,确定了加筋格宾结构的滑动破裂面形状,提出了一整套该新型结构的计算与设计方法。The reinforced earth retaining wall with double twisted steel wire mesh and gabion is a new type of retaining wall which reinforcement is twisted steel wire mesh produced by factory and there is no joint between face wall and wire mesh. Few examples of its application in China can be found, its theory and design method has gotten less advancement and can not meet the engineering needs. The studies show that the stability of this structure is better than conventional reinforced earth retaining wall such as bar-reinforced and geogrid-reinforced retaining wall and it is propitious to be used in building high retaining wall and retaining wall used in high grade highway. After absorbing foreign advancing reinforcement technology, the design parameters were determined by tensile and pullout tests, the form of failure surface was studied by indoor large scale model test and a complete set of calculation and design method was put forward in this paper.
