Introduction Currently, the deterministic method based on safety factor often used in the reliability analysis of retaining wall and the long-term application in engineering proves it is an effective and practical method, however, because of the material inhomogeneity, random and the variability of spatial, some of the retaining wall is safe according to the method, however damaged when put it into use.

Material properties of products (such as plastic melt liquidity, etc.), injection molding process parameters (including injection rate, holding pressure, melt temperature, mold cavity temperature, etc.), the mold structure (such as gate location, gate number, etc.) and plastic parts structure (such as the presence of holes, wall thickness is not equal, etc.), are the main mechanism and factors that produce weld mark [2].
