全风化花岗岩边坡冲刷机理及工程防护措施

摘要

Due to its special engineering properties, the completely weathered granite is become the ecological environment and engineering conditions fragile area. The erosion of the completely weathered granite slop is very serious, and the slope design often ignored erosion' s influence to the safety of completely weathered granite slope. So, the paper analyses the critical height and the initial erosion length of the weathered granite slope, and provide the protection measures and reference for the similar slop design and construction.%全风化花岗岩由于工程性质特殊,成为生态环境和工程条件脆弱区.在公路工程中全风化花岗岩边坡坡面冲刷严重,而目前公路边坡设计中往往忽视冲刷对风化花岗岩边坡安全的影响.为此,结合工程实际,分析得出了全风化花岗岩地区边坡冲刷防护的临界高度和起始冲刷长度,并有针对性的提出了相应的工程防护措施,为同类边坡的设计和施工提供参考.
