Abstract Sinusoidal curved lateral resistance method(SCLRM) is the theoretical correction for triangular method. Considering the nonlinear characteristics of soft，underwater soft plastic and composite strata that the large diameter tunnel passing through，the lateral resistance was corrected in SCLRM. The theoretical formulas of SCLRM were derived and the example was shown. Based on the free-form deformation method(FFD)，the internal force distribution for the lining structure were calculated using triangle method and SCLRM. The scope and restriction of the application of theory were expanded. The applicability of each lateral resistance method in actual complex formations was discussed. Comparing the measurement value with theoretical results for Nanjing subway line one，it is indicated that the internal force calculation of single round integral type shield tunnel by SCLRM having a definite procession and a small error range which are suitable for this engineering example design. Application of this example provided a theoretical reference of internal force maximum value for designing single round shield tunnel passing through the composite strata. It seems that SCLRM has the certain practicality for similar project design.

Key words： tunnelling engineering curved lateral resistance method force method derivation optimize of the resistance coefficient internal force calculation of lining applicable conditions
