passive earth pressure 中文意思是什麼
passive earth pressure
解釋
被動地壓-
Now some universities and institutes of china have made some samples of the lunar rovers and theirs wheels, but until now the wheel ’ s mechanical performance is seldom researched and tested. this paper will analyze the mechanical performance of the wheel and design a test - bed to test the performance of the lunar rover ’ s wheel. firstly, the mechanical characters of the soil are separated to press - sinkage character and shear character based on bekker ’ s theory, and common press - sinkage and shear models are introduced and the theory of lankine passive earth pressure is also introduced
根據bekker半經驗法的基本思想，將土壤的力學特性分解為水平方向的剪切特性和豎直方向的承壓特性，闡述了地面力學中常見的土壤的承壓、剪切等力學模型，並引入了朗肯被動土壓力理論，為建立車輪在松軟土壤中前進和轉向的力學模型奠定了基礎，同時進行了實驗土壤的剪切實驗，測量了土壤的內聚力和內摩擦角等參數。 -
These basic theories are helpful to construct model. some parameters of soil used for experiments are measured by shear experiments. secondly, mechanical models of the wheel - soil interaction when rolling and steering are constructed respectively based on the theory of terrain - vehicle and passive earth pressure
基於地面力學中的bekker承壓模型和janosi剪切模型，建立了一種月球車車輪在松軟地面上前進時的力學模型，根據被動土壓力理論，建立了該車輪在轉向時的力學模型，給出了所建方程及模型的數值解法。 -
Based on the hypothesis that the rear side of retaining wall is pitching and coarse, and the filling surface is gradient, taking viscous filling as the object of study and using the static balance method, a study has been conducted on the earth pressure on the rear side of retaining wall under the sliding wedge ' s limiting equilibrium condition, and generated a general form for active earth pressure and passive earth pressure
摘要基於擋土墻墻背俯斜、粗糙且填土表面傾斜的情況，以粘性填土為研究對象，用靜力平衡方法研究了擋土墻后滑動土楔體達到極限平衡狀態時作用於墻背的土壓力，提出了主動土壓力和被動土壓力的一般形式。 -
