降雨诱发路基病害预报预警研究

Prediction and Early Warning of Subgrade Defects Caused by Rainfall

降雨作为诱发路基病害最为重要的因素之一,由于其诱发的路基病害破坏程度深、影响范围广、后果比较严重,因此,对降雨诱发的路基病害进行预测预报就显得尤为重要。选取张涿高速公路保定段的路基边坡进行研究,通过建立可靠的预报预警模型对降雨可能导致的路基病害进行预测,从而对路基病害进行预防性养护治理,避免了危害的发生。

Rainfall is one of the most important factors that cause the roadbed defects with severe consequence in terms of the scope of the impact and damage extent. Therefore, it is very important to forecast and make early warning to the damage caused by rainfall. The side slope of subgrade on the Baoding Section of the Zhangjiakou to Zhuozhou Expressway Project is selected to establish a reliable forecast and warning model to predicate the potential damage to the subgrade, and thereafter to make preventive maintenance and treatment to the subgrade defects and avoid the damage to the subgrade.
