一、序言美军工程兵水道试验站(WES)在建立经验的土壤—车辆关系时,成功地用圆锥指数(CI)作为描述土壤强度的一个指标,以予测履带式车辆的性能,CI 是土壤对于正圆锥体贯入阻力的量度,虽然被用为无量纲指数,但它实际上是作用于贯入仪把手上的力(以磅计),除以圆锥底面 I. INTRODUCTION The US Army Corps of Engineers Hydrological Station (WES) succeeded in using the cone index (CI) as an indicator of soil strength to establish the performance of a tracked vehicle when building an experiential soil-vehicle relationship (CI) The measure of the positive cone penetration resistance, though used as a dimensionless index, is actually the force (in pounds) acting on the penetration handle divided by the cone underside
