【摘要】 钢筋混凝土格构锚固是滑坡治理的一种有效措施,在三峡工程地质灾害治理中应用广泛。在钢筋混凝土格构梁与预应力锚索复合结构受力分析的基础上,提出了格构锚固的力学模型,将格构梁简化为受集中力作用的弹性地基上的梁,并按无限长梁和有限长梁上受一个集中力和多个集中力作用,分别推导出变形和内力分布表达式,讨论了格构梁工程设计的基本要求,提出了格构梁工程设计的步骤和方法。以三峡工程库区巴东县太矶头滑坡为例,系统介绍了该滑坡治理设计的实施过程。更多还原

【Abstract】 Lattice frame anchor structure is an effective engineering measure in landslide control and widely used in the reservoir area of the Three Gorges Project. The design theory and method of the structure are studied systematically. On the basis of the force analysis of prestressed cable lattice beam, mechanical model of lattice frame anchor structure is proposed and the formula of deformation and inner force of the beam with finite and infinite distance conducted respectively. The engineering design demands, steps and methods are put forward according to the research. Taking Taijitou landslide in Badong County of the Three Gorges reservoir region as an example, lattice frame anchor structure is applied to the control project design; and the design process is introduced in detail.更多还原
