摘要
由于雨水在同步碎石封层面上形成一层薄层水膜,在行车荷载作用下产生动水压力,而动水压力大小主要与行车速度有关,在不同的行车速度作用下,产生的动水压力对同步碎石封层影响不同。文章主要通过室内模拟试验,研究和分析不同行车速度下产生的动水压力对同步碎石封层病害产生的影响。
The rain can form a thin water film on the synchronous crushed stone surface layer,which will generate dynamic hydraulic pressure under the driving load.Whereas,the strength of dynamic hydraulic pressure is mainly related to the driving speed.Under different driving speed,the synchronous crushed stone surface layer will be subject to different impact by dynamic hydraulic pressure.Based on the indoor simulation test,the Paper studies and analyzes the impact of dynamic hydraulic pressure on the defect of synchronous crushed stone surface layer,which is generated under different driving speeds.
