以侵彻原理为基础建立起气动矛有效工作约束条件;在土动力学基础上,以饱和砂土为例建立起气动矛受土壤力的模型,分析了在不同土壤力学特性下,气动矛穿越土质及穿越过程中受土壤力大小的影响因素. On the basis of soil dynamics, taking the saturated sand as an example, a model of pneumatic force subjected to soil was set up. Based on the analysis of the different soil mechanics characteristics, Soil and through the process by the impact of soil strength factors.
