摘　　要：作为一种典型的灾害地貌过程 ,泥石流是山区公路重要的水毁类型之一。本文基于对西部公路沿线发育的泥石流水毁的调研 ,将穿越泥石流沟的公路结构形式概化为涵洞、桥梁和过水路面。将泥石流水毁的宏观表象概化为桥台泥石流水毁、上部结构泥石流水毁、桥台基础掏蚀、泥石流淤埋桥涵、泥石流水毁路基等类型。并用新构造应力场的观点探讨了泥石流水毁发育的宏观规律 。As one typical catastrophic geomorphologic process, debris flow is one of important damage induced by water of highway. On the basis of investigation in situ to Highway Damage Induced by Debris Flow(HDDF) along highways in the west of China, the authors divide highway structures to pass debris flow valley into culvert, bridge and ford in this paper. Further, according to macroscopic features of HDDF its general model is divided into abutment damage, upstructure damage, abutment erosion, bury of culvert and bridge, and roadbed damage induced by debris flow. The authors approach macro features in view of new tectonic stress field. The results are a guide to study and control HDDF.
