为强化山区高速公路弯道交通安全保障，本文通过对现有文献研究和公路交通弯道交通安全事故统计分析，建立了以弯道曲线半径、坡度和曲线数量、高填方和高边坡等危险性工程为指标的山区高速公路小半径路段危险性分级的3级标准，并给出了人、路、环境相结合小半径路段交通安全保障设施设置建议。结合江西德上高速公路实际情况，统计识别了德上高速K1－K30桩间CA级小半径路段6处，CB级小半径路段3处，并提出了相应的交通安全保障设施建议，以提升山区高速公路交通安全保障水平。

In order to strength the traffic safety of small radius sections in mountainous highways ,firstly the existed papers are studied and the curve traffic accidents in highways are analyzed ,then the three-level classifications for the danger levels of small radius sections in mountainous highways are established with turning radius ,slope and curve number ,dangerous projects such as high fill engineering and high slope engineering as indexes and finally it is pointed out that the traffic safety facilities setting of small radius sections should be considered with people ,road and environment together .Combined with the situation of De-shang highway ,it is shown that there are 6 CA-level sections and 3 CB-level sections of small radius from stake K1 to K30 and then some advices on the traffic safety facilities are put forward to improve the safeguard level of traffic safety in mountainous highways .
