It is found that in certain water ratio and consolidation pressure, the values of initial elastic modulus and principal deviator stress increase with intermediate principal stress increasing; in certain intermediate principal stress, the values of initial elastic modulus and principal deviator stress increase with water ratio falling.

试验结果表明：在一定的含水率和固结压力下，偏差应力和初始切线模量均随中主应力比b的增大而增大；在中主应力比b确定的情况下，偏差应力和强度最大值随着含水率的增大而减小。

The first proposes that any differentiable function defined on an interval has a mean value, at which a tangent line is parallel to the line connecting the endpoints of the function's graph on that interval.

In this paper, the marshland of Daxinganling forest region is classified into three kinds, the pass performance of three kings of crawler fire engine, J-50, A531, BFC804 and a kind of two-wheeled forest fire engine of special light-duty HS-8 is studied in theory and test, the calculation formulas of the tangential traction force and the external motion resistance of vehicle are given and the drawbar pull is used as evaluation index.

对大兴安岭林区的沼泽地进行了分类，并对3种履带式森林消防车J-50、A531、BFC804和一种特轻型双轮森林消防车HS-8的沼泽地通过性作了理论与试验研究，给出了切线牵引力和行驶阻力的计算公式，采用挂钩牵引力作通过性评价指标。结果表明，BFC804可以通过重沼泽地，A531和HS-8可以通过中沼泽地，而J-50只能通过轻沼泽地。
