4、制宜、以防为主、确保施工”是边坡综合防护设计的根本准绳。(2)路基防护应依照设计、施工与养护相分离的准绳,深化调查研讨,依据当地气候环境、工程地质和资料等状况,量体裁衣因地制宜,选用恰当的工程类型或采取综合措施,以保证路基的稳定。不要随便取消或减少必要的防护工程措施,而给养护遗留繁重的工作量。(3)路基防护措施是依据沿线不同土质岩性、水文地质条件、坡度、高度和当地资料、气候等量体裁衣选择,亲密分离路面排水作综合思索。(4)在不良的气候和水文条件下,对粉砂、细砂与易于风化的岩石边坡,以及黄土和黄土类边坡,均宜在土石方施工完成后及时
5、防护。路堑边坡应依据边坡岩层组成及坡面弱点散布状况思索全面防护或部分防护。(5)坡面防护普通不思索边坡地层的侧压力,故请求防护的边坡有足够的稳定性。但护面墙可用于极限稳定边坡。"Integrateddesign,adjustmeasurestolocalconditions,incaseisgivenpriorityto,toensurethatconstruction"isthebasiccriterionofslopecomprehensiveprotectiondesign.(2)theroadbedprotections
