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。 -

In this paper, based on the analysis of the rlem of theory foundation, computing method, preference, applicability, etc, we anatomized the rlem of three self - deficiencies and six scarcities. moreover, we adopted the parallel ways of contrasting the rlem with the fem and applied it to analyzing the impact of slide block of elasticity and plasticity, slip surface of coefficient and slip bed of elasticity, plasticity upon the stability of slope and in the plain linearity slope, the plain refracted line slope and the plain arc slope. in addition, we discussed the warp of between the lem of ( sarma, janbu, order, bishop, morgenstera - price, etc ) and the fem of result and the distributing of positive stress and shear stress on the slip surface
本文從剖析剛體極限平衡法的理論基礎、計算方法、參數選取、適用條件等方面入手，剖析了剛體極限平衡方法的3點自身缺陷和6點不足，並在此基礎上採用了剛體極限平衡法（平面滑動破壞法、 sarma法、傳遞系數法、普遍條分法、 janbu法、 bishop法、 morgenstern - price法）與大型有限元法對比研究的方法，分析研究了平面直線型滑坡、平面折線型滑坡、平面圓弧型滑坡在漸進破壞中邊坡的滑體彈塑性參數、滑麵塑性參數） 、滑床的彈塑性、以及極限平衡法無法考慮開挖應力釋放等因素對邊坡穩定性的影響與滑動面上的正應力、剪應力分佈規律、安全系數的解答的差異。 -
Through analyzing bed ' s response to wave, in the condition that super - stratum is more hard and second - stratum is more soft in region of interest, super static interstitial hydraulic pressure amplitude die away rapidly between stratums, before in sight of boundary between hard and soft stratum, plane effective pressure increase to max. shear stress reach peak value when bed thickness is approximately 2. 7 meters, then it will decrease to the minimum on the place where the flexible soil has a common boundary with the rigidity, so the boundary is the most destroy plane on engineering. on the basis of reconnaissance in situ, in normal situation of sea, the structure slides to the basin along the boundary
通過對底床在波浪下的響應分析，對于研究區底床上層較硬而第二層較軟的情況，超靜孔隙水壓力幅值在層間交界處迅速衰減，在臨近硬、軟地層交界處前，水平有效應力增至最大，剪切應力在底床厚度大約2 . 7米左右達到峰值，然後減小，到硬、軟層土交界位置，達到最小，因此這個界面就是最容易發生破壞的工程軟弱面，現場勘查證明，即使在正常海況下，構築物也會沿坡以此交界面為滑動面，緩慢向「盆」底滑動。 -

Ann is a adaptive and non - linear dynamic system made from superposition of many simple components which we call neuron. the question for computation of d _ ( cmax ) belongs to incipient motion of sediment in essence, which is the same question with two different sides, because computation of critical condition ( including critical velocity critical shear stress critical power ) for a grain size under a bed - load condition is equal to computation of a grain size during incipient motion under the bed - load condition and the water flow condition given before. and computation of gross bed - load transport rate has great relationship with standard of incipient motion
對于d _ （ cmax ）的推求，在本質上還是泥沙的起動問題，因為尋求某種床沙條件下某級泥沙的起動條件（如起動流速、起動切應力、起動功率）和尋求某種水流和床沙條件下的起動粒徑是同一問題的兩個方面而已；而對于推移質總輸沙率推求也和泥沙起動問題中的起動標準選擇緊密相關。 -
A numerical calculation is developed about the response of sea - bed to wave loading on the yellow river delta. we find that : ( 1 ) the effects of wave parameters and soil characteristics on the response of sea - bed to waves are obvious : wave height and wave length are important parameters among wave parameters ; shear modulus is dominating parameter among soil parameters

Excellent correlation exists between the distribution of bottom shear stress and that of sediment types. low shear stress occurs in the central mud area ; where only fine - grained sediment can be imported by weak tidal currents. once settled into the bed, it is difficult for set the sediment into motion
中部泥區為應力低值區所在，水動力弱的中部泥區只能接受弱水動力帶來的細顆粒物質，而且這些細顆粒物質一旦沉積下來，便難以再懸浮搬運走，說明中部泥區是連續沉積細顆粒物質沉積區。
