本文介绍一种用于整治大滑坡的新型结构物,其形状与椅子相仿。这种结构物在枝柳线施溶溪滑坡整治工程中被首次采用,它由锚固桩、承台、上墙和拱板等组成。本文简要地论述了椅式桩墙的设计原理和计算方法。根据现场实测数据,分析研究了混凝土桩孔护壁和椅式桩墙的受力和工作状态,以及滑坡推力的分布。由于设计中考虑了地基土的垂直摩擦力、水平摩擦力、侧向抗力和框架结构的共同作用,结构较为合理。椅式桩墙是一种造型美观,整治滑坡效果好的支挡建筑物,可以在工程上应用。
This article presents a new structure for the treatment of large landslides that has the same shape as a chair. This structure was used for the first time in the treatment of the Liuxi Creek Ridge Treatment Project in Zhiliu County. It consists of anchoring piles, caps, upper walls and arch plates. This article briefly discusses the design principle and calculation method of the chair pile wall. According to the field test data, the force and working status of the concrete pile wall and the chair pile wall as well as the distribution of the thrust of the landslide are analyzed and studied. Due to the design of the vertical soil friction, horizontal friction, lateral resistance and the framework of the joint action, the structure is more reasonable. Chair-style pile wall is a beautiful shape, landscaping effect of retaining the retaining buildings, can be applied in engineering.
