Caisson sinking is a vital process in marine engineering, and accurate simulations are crucial for predicting and preventing potential accidents or failures. Current numerical simulations necessitate measured engineering parameters, constraining their applicability. This study utilized the coupled Euler-Lagrange (CEL) method to compute specific parameters. These parameters served as substitutes for the engineering measurement values to enhance the static simulation process for the incremental height sinking of caissons, thereby addressing the constraints set by engineering measurements. The CEL method was initially utilized to simulate a dynamic permeation process, generating a series of valuable parameters such as the degree of caisson sinking and mud surface depth at the cavity bottom. Using these parameters instead of engineering measured parameters, a stable state model for incremental height sinking of caissons was established, followed by a static analysis. The improved method was subsequently applied to simulate the construction process involving caisson sinking, demonstrating its feasibility. This enhanced static simulation provides a novel approach for examining the equilibrium state of caisson subsidence, eliminating the need to wait for the actual construction phase to be completed. The proposed method exhibits the critical advantage of favorable predictability, allowing for the anticipation of potential mishaps, such as abrupt subsidence, and supplying timely cautionary information to facilitate proactive measures, ultimately reducing the incidence of engineering accidents or failures.
