| 摘 要： | 针对川藏公路东久河下游段特殊水文水力条件和自然环境特征，选择(K4113 280～K4113 365)典型水毁段为例，对该段路基水毁的形成因素、特征、活动规律及公路路基水毁防护经验教训分析，根据野外路基防护工程冲刷模拟试验，建立适合该段路基护墙冲刷深度计算公式，在保证足够基础埋深的基础上，提出了浆砌石挡土墙 钢丝网混凝土护坦的长期(永久性)防护工程方案，为西藏高山峡谷区沿河路基水毁防护工程建设提供了示范。

| Abstract: | A case study is carried out in Dongjiu river, the lower reach of the Tibet-Sichuan Highway, between milestones of K4113 280 and K4113 365, where water destructions are intensive and representative in gorgy areas in Tibet. Causes, types, and features of water destructions are studies in detail. And, based on simulation experiments, empirical formulas are established to estimate washing depth of roadbase in the section. According to the result, a strategy for eternal prevention is put forward claiming a structure in combination of masonry counterfort and concrete apron with steel reticulation, which would be of practical importance in water-destruction prevention in Tibet. |
