【摘要】 砂质土地区的特点是土壤中的含砂量较高 (在 35 %之间 ,砂漠地区则更高 ) ,含水量低 ,因而土壤呈流砂性 .在非路面地带 ,土壤未经压实 ,表现为干砂性壤土性质 .轮式车辆在这些地区行驶时 ,往往会产生涌土现象 ,阻碍了车辆的运行 .行驶功率不是消耗在克服牵引阻力上 ,而是消耗在对土壤的压实上 .该功率消耗量的大小 ,可通过本文的分析加以确定 .从而获得解决该问题的思路更多还原

【Abstract】 The arenaceous soil contains more sand and less water.So,it is of flowing peculiarity.When the vehicle runs on the trackless zone whose soil is uncultivated and dry,there will be surging soil performance with soil embarrassing the wheels.Power is not consumed by drawing but by pressing.This article analysed the amount of consumption power so as to find a way to solve the problem.更多还原
