巴基斯坦湿陷性黄土路基浸水试验研究

Soaking Test of Collapsible Loess Roadbed in Pakistan

在巴基斯坦湿陷性黄土路基试验段,运用大型原位浸水试验,研究路基浸水后柱锤冲扩桩和挤密桩地基的浸水规律以及地基土湿陷对路基沉降的影响。研究结果表明:在实际工程中,一定要加强挤密桩路段的防排水措施,避免局部积水,以保证行车安全。

In the experimental section of collapsible loess subgrade in Pakistan,a large in-situ flooding test was conducted to study the rule of water infiltration of the subgrade after the subgrade was immersed in water,and the influence of the subgrade soil subsidence on the subgrade settlement.The results show that in the actual project,it is necessary to strengthen the prevention and drainage measures of the compacted pile section to avoid local water accumulation and ensure driving safety.
