摘要
高速公路建设不可避免地会对沿线生态环境造成影响,主要体现在引发景观破碎、水土流失、地质灾害等方面。不同特征的边坡进行生态防护时,其所采取的防护对策及技术是有所不同的。从边坡生态防护角度将公路边坡类型分为3种,即景观恢复型、防地质灾害型和防水土流失型,所对应的边坡稳定程度从稳定、浅层不稳定到深层不稳定,因此,在3种类型边坡的防护要求、综合防护对策与技术上要有所差异。分析了3种类型在公路建设中产生的特征及其防护对策与技术措施。
Building of highway slop has negative effects on environment inevitably, mainly including arousing geologic calamities, destroying natural sight, and water and soil loss. However, these effects happened at the same time. For protection engineering of highway slop, the special emphasis of protecting measures and techniques will be laid on different types of environmental protection. Comprehensive protection for highway slop was divided into three types, namely natural-sight-recovering type, geologic calamities type, and water and soil loss type. The stabilization degree of these three slop type are from stable, shallow unstable to deep unstable. Characteristics, measures and techniques of comprehensive protection were discussed for every type in this paper.
