项目摘要
It has been observed that pore-air pressure affects unsaturated seepage behavior in unsaturated soils. It has also been reported that a large number of air bubbles can develop in soils after a river dike failure resulting from a flood. In this project, laboratory tests using a cylindrical soil box and a soil tank to investigate the behaviors of the pore-water pressure and the pore-air pressure under the different rainfall intensity and boundary conditions are reported. The behaviors of the pore-water pressure and pore-air pressure measured by a field monitoring are also described. As the results, these results suggest that measuring of the pore-air pressure clarifies the behaviors of pore-water pressure in unsaturated soil.
据观察,孔隙空气压力影响非饱和土壤中的不饱和渗流行为。另据报道,洪水导致河堤溃决后,土壤中会产生大量气泡。在该项目中,报告了使用圆柱形土箱和土箱进行的实验室测试,以研究不同降雨强度和边界条件下孔隙水压力和孔隙空气压力的行为。还描述了通过现场监测测量的孔隙水压力和孔隙空气压力的行为。因此,这些结果表明,孔隙气压的测量可以阐明非饱和土中孔隙水压力的行为。
