摘要:

针对西安市某城市立交黄土路基,基于不同时段特征交通荷载频率现场监测结果分析影响频率,建立了非饱和黄土路基动载-渗流耦合模型试验箱,探明了荷载类型以及动载频率协同管道泄流作用下体积含水率、孔隙水压力、基质吸力等参数的变化趋势。结果表明:车辆动载影响下的路面振动优势频率范围为5～25 Hz; 在不同荷载类型影响下,所有监测点体积含水率、孔隙水压力、基质吸力的变化趋势相似; 动载条件下的体积含水率高于静载条件,而基质吸力、孔隙水压力反之,响应时间滞后是由监测点埋深较远导致的; 泄流孔附近的渗透行为突出,入渗速率高达33.3 mm·min^-1,对应的运移时间最短(0.6 min); 若动载频率介于交通振动的优势频率(18～22 Hz)之间时,极易导致共振危害。

Abstract:

Aiming at an city interchange loess roadbed in Xi'an, based on the field monitoring results of characteristic traffic load frequency in different periods, the influence frequency was analyzed, and the unsaturated loess roadbed dynamic load-seepage coupling model test box was established. The variation trend of parameters such as volumetric water content, pore water pressure, matrix suction and other parameters under the action of load type and dynamic load frequency synergistic pipeline leakage was explored. The results show that the dominant frequency range of pavement vibration under the influence of vehicle dynamic loads is 5-25 Hz. Under the effect of different load types, the variation trends of volumetric water content, pore water pressure, and matric suction at all monitoring points are similar. The volumetric water content under dynamic load conditions is higher than that under static load conditions, while the matrix suction and pore water pressure are on the contrary. The lag in response time is attributed to the relatively large burial depth of the monitoring points. The seepage behavior near the drainage holes is prominent, the infiltration rate reaches up to 33.3 mm·min^-1 and the corresponding migration time is the shortest(0.6 min). If the dynamic load frequency is between the dominant frequency of traffic vibration(18-22 Hz), it is easy to cause resonance damage.
