Christian and Wong [2] pointed out that excavation simulation in linearly elastic material is independent of the number of increments used for excavation process, but for the finite elements they used, this criterion did not hold.
Christian and Wong indicated that the errors may be caused by the factor that the lower-order linear triangle and four-node quadrilateral elements are inadequate to model the stress gradients near the corner of the excavation.

P.W.Wong proposed the first watermark model [3].
Meanwhile P.W.Wong’s model converts a watermark image A into M×N pixels picture which has similar blocks, digital abstract and Ai corresponding XOR with the original image.

In 1956, Bekker [1] formulated a relationship between sinkage pressure and shear stress of a wheeled vehicle on soft ground; Wong (1984) [2]developed an analytical method for predicting the normal pressure distribution under a moving tracked vehicle, taking into account the response of the terrain to repetitive shear loading.
According to Wong, this relationship can be obtained by equation(2): (2) Here, is the shear stress of the soil,denotes the maximum shear stress,is the ratio of the residual shear stress to the maximum shear stress,and is the shear displacement where the maximum shear stressoccurs. can be obtained by equation(3): (3) Here, and are the cohesion of the soil and the angle of internal shearing resistance of the terrain respectively.
