【摘要】 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.更多还原

【Abstract】 An efficient bound model of impact mole penetrating through the saturated soil is established.Under the different soil conditions,the features of the saturated soil and the impacting factors on which whether the impact mole can penetrate through the soil are analysed on the basis of setting up the mathematical model.更多还原
