Initial Results of a new Free Fall-Cone Penetrometer (FF-CPT) for geotechnical in situ characterisation of soft marine sediments
Initial Results Free Fall-Cone Penetrometer situ characterisation soft marine sediments
2009/12/3
Two of the most crucial sediment physical parameters controlling slope stability and trigger mechanism of mass movements are shear strength and excess pore pressure. Since both of them require in situ...
设计了一种应用滚珠丝杠传动、直流电动机驱动的恒速(30mm/s)土壤圆锥指数测量装置。将电动机驱动滚珠丝杠传动方式应用于土壤参数测量装置,具有较高的运行控制精度和机械传动效率。在机电一体化设计方面,研制的专用微控制器既负责协调土壤坚实度信息与纵向行进深度动态信息的实时获取和运行状态监控,又同时与GPS模块和PDA连接。充分利用PDA提供的软硬件资源,可实现农田数据的大容量存储和智能化信息处理。田间...
