The invention discloses a'minimally invasive 'combined structure suitable for a half-excavated and half-filled roadbed on a steep cross slope, and belongs to the technical field of highway engineering. The structure is composed of slide-resistant piles, pre-stressed anchor cables, cantilever beams, pavement slabs, breast boards, short columns, expanded foundations, anti-collision guardrails and other main components. Various supporting forms are organically combined, the roadbed slope is supported, blocked and anchored on the side close to the mountain through the slide-resistant piles, the pre-stressed anchor cables and the breast boards, a part of the roadbed structure is overhung on the outer side of the mountain through the cantilever beams to replace a common fill roadbed, and the disturbance range of the roadbed structure on the natural mountain is effectively reduced. The supporting and retaining device has the multiple functions of slope supporting and retaining, mountain anchoring, road surface cantilever supporting and the like. The structural stability and reliability are good, the construction difficulty is moderate, the environmental and economic benefits are good, a minimally invasive structural scheme is provided for the structural design of the half-excavated and half-filled roadbed on the abrupt slope, and the method has application and popularization value in the technical field of highway engineering.
本发明公开了一种适用于陡横坡上半挖半填路基的“微创型”组合结构，属于公路工程技术领域。本发明由抗滑桩、预应力锚索、悬挑梁、路面板、挡土板、短柱、扩大基础、防撞护栏等主要构件组成。本发明将多种支护形式有机组合，在靠近山体侧通过抗滑桩、预应力锚索和挡土板对路基边坡支挡锚固，并通过悬挑梁将一部分路基结构悬挑在山体外侧代替普通填方路基，有效减小了路基结构对自然山体的扰动范围。本发明具有边坡支挡、山体锚固、路面悬挑支撑等多功能。结构稳定性和可靠度较好、建造难度适中、环境和经济效益倶佳，为陡坡上半挖半填路基结构设计提供了“微创型”结构方案，在公路工程技术领域具有推广应用价值。
