从某一高加筋土挡墙发生局部破坏的工程事故中发现该种挡墙的设计还存在一些问题,如加筋区与墙面板的沉降差过大,导致筋带受力条件的恶化;胸墙设置不当,会导致其内倾,从而造成墙面板上部外倾。此外筋带与面板的连接构造以及筋带的性能也会产生一些问题。鉴于高加筋土挡墙是重要建筑结构,而又没有成熟的理论及设计和施工规范,故仅对其破坏形式及其形成原因进行探索性研究,并初步建议了一些改进方案。
Some engineering problems such as partial settlement of a high-reinforced earth retaining wall have been found, such as the difference between the settlement of the stiffened area and the wall slab is too large, which leads to the deterioration of the stress conditions of the tendons. Improper placement of the chest wall can cause it to tilt inward, causing the upper part of the wall panel to be camber. In addition, the connection between the rib and the panel and the performance of the rib also cause some problems. In view of the fact that the high-reinforced earth retaining wall is an important building structure without mature theories and design and construction specifications, only the exploratory research on the form of damage and its formation is made and some improvements are proposed.
