variable-speed cone

The method is based on the following concepts: ( 1) semi-bending moment theory combined with boundary effect theory of the cone-cylinder Junction ( 2) the minimun potential energy principle with the tangential displacement as the fundamental variable.

该方法的基本思想是：（1）联合运用半弯矩理论和结合边附近边界效应理论；（2）利用以切向位移作为基本未知数的最小势能原理。

The method consists in carrying out penetrometer tests with a portable dynamic penetrometer of variable energy in natural and saturated conditions as a first step, a compressibility test ( static loading test) is then performed after the cone penetrometer tests.

该方法的试验程序是，先用轻便可变动能触探仪在天然状态和饱水状态下进行触探试验，而后在触探孔完成静载荷压缩性试验。
