Abstract: There are about 85 000 reservoirs in China now, and some dam crest are used as important traffic roads. Generally, the damcrest as an important traffic road is of bad influence on damproject. By comparing the safety factors of structural static stability against sliding and aseismatic stability of reservoir damslope in situation that with traffic loads and with no traffic loads, this paper put forward the conclusion that the damtop road has little effect on damsafety. Its result can be used for reference in damslope stabilitiy safety analysis.

摘要: 我国现有8.5 万多座水库大坝, 其中不少水库的大坝坝顶作为交通公路使用。一般, 水库大坝坝顶作为车辆行驶的重要公路, 会对大坝工程安全造成一定程度的不良影响。本文通过分析坝顶公路有无车辆、人群荷载两种情况下某水库大坝坝坡结构静力抗滑稳定和抗震稳定的安全系数, 说明坝顶公路对大坝工程安全的影响较小, 可为水库大坝坝坡稳定安全分析提供借鉴。
