摘要
在山区高速公路中,对于路基挖方量大、路堑边坡高、地质较差地段一般多采用预应力锚索格子梁,可以有效地整治滑坡,达到稳固边坡的目的。结合贵阳至遵义公路扎佐至南白段改扩建工程滑坡设计与施工,根据坡体特征、成因,简要介绍预应力锚索防护高边坡的施工工艺及技术,并就预应力锚索防护高边坡的施工方法提出了几点建议,以供同仁们探讨和借鉴。
For the expressway of the large-excavation subgrade,high-slope cut and the poor geological section in a mountain area,the prestressed tendon lattice girders are adopted to effectively treat the landslide and stabilize the side slope.Combining with the design and construction for protecting against the landslide in the rehabilitation and extension project of Zhazuo-Nanbai section of GuiyangZunyi Highway,the construction technology of the prestressed tendon for protecting against the landslide of the high side slope is briefly introduced and some suggestions are put forward.
