摘　　要：国道217线天山公路地处山岭重丘区,其中K962~K1040段沿库车河布设,很多路段地处凹岸,河流对路基造成的冲刷水毁病害严重。勘察设计阶段拟采用护墙、护墙＋护坦、护墙＋丁坝等型式进行路基防护,但其防护的效果在本阶段难以验证,因此,通过对典型的K970＋450~K970＋850水毁段进行冲刷模型试验,研究了各种防护型式的效果和存在的不足,并依据试验成果优化了设计方案,取得了良好的效果。Tianshan Road of G217 is located in mountainous areas,the K962 ~ K1040 segment laid along the Kuche River,and many road sections are located in the concave bank of the river,which lead to serious water erosion on the roadbed. Design phase adopted parapet,retaining wall,retaining wall＋ apron,retaining wall ＋ Spur dike etc to prevent water damage. but the protective effect is difficult to verify at this stage,so,Through the K970 ＋ 450 ~ K970 ＋ 850 segments erosion model test to study the effects of various types of protective,And based on the test results to optimize the designs,achieved good results.
