摘要

Object: This paper is concentrated on soil body's stability and economy of the shield end and its reinforced thickness. Methods: Existing elastic thin plate model was too conservative for design. A modified elastic plate model of the thickness was proposed for calculation. Based on elastic finite element analysis data, optimal fitting was carried out for the proposed elastic model. and the coefficients of the model were obtained. Results: The maximum bend stress of the model of elastic thin plate is higher than that of the modified model of elastic plate. It has been manifested by the calculations. The model of elastic thin plate is more conservative and its degree is determined by the ratio of thickness to diameter of the plate (t/D). The finally value of the thickness in practice is between the value of elastic thin plate model and the value of modified elastic plate model. Conclusion: It has proved that the suggested model is useful for engineering practices, and extends theoretical methods for calculating the reinforced thickness. In engineering practices the model of elastic thin plate and the modified model of elastic plate should be used to calculate the reinforced thickness synthetically.
