Numerical Assessment for the Behavior of the Pleistocene Marine Foundations due to Construction of the 1st Phase Island of Kansai International Airport

Interactive behavior of Pleistocene marine foundation of existing 1st phase island due to construction of 2nd phase island of Kansai International Airport

“…Mimura and Jeon (2011) proposed a representative ground model in which continuous horizontally even layers with a constant thickness were assumed based on the boring data at monitoring point 1 of the 1st phase island. It is confirmed that the adopted numerical procedure using the concepts of "non-elastic behavior in the quasioverconsolidated region" for the Pleistocene clays and "mass permeability" for the Pleistocene sand gravel layers could describe the overall behavior of the reclaimed Pleistocene foundation due to the construction of the 1st phase island of KIX.…”

“…The adopted procedure for the numerical analysis is the one proposed by Mimura and Jang (2004). It should also be noted that the concept of mass permeability is applied as a reasonable modeling for the Pleistocene sand gravel layers, as reported by Mimura and Jeon (2011). Attention is paid to the interactive behavior of the reclaimed foundations due to the adjacent construction of the 1st and 2nd phase airport fills.…”

“…It was reported that a realistic modeling of this non-linearity of the e−log p relations for the Pleistocene clay could provide the advance in settlement without sufficient dissipation of excess pore water pressure. Mimura and Jeon (2011) proposed a representative ground model to describe the compression of the individual Pleistocene clay layers together with the generation and dissipation process of the excess pore water pressure at the center of the 1st phase island of KIX, over a 13-year period, due to the construction of the 1st phase island. Note that the assumption of the non-elastic behavior in the quasi-overconsolidated region for the Pleistocene clay (Mimura and Jang, 2004) and the concept of "mass permeability" of the Pleistocene sand gravel layers that control the consolidation of the reclaimed foundation at KIX have been introduced in the numerical procedure .…”

Numerical Analysis of Soil Settlement Prediction and Its Application In Large-Scale Marine Reclamation Artificial Island Project

“…Cheng Xiang and Tongling Zhou [15,16] studied consolidation settlement of the bank protection structure of the artificial island by using the creep model for numerical simulation, analyzed sensitivity of key parameters, and summarized the response law of the settlement results. Mamoru Mimura [17] studied consolidation settlement of the No .1 runway of the Guangxi International Airport. The actual monitoring values are roughly consistent with the finite numerical calculation results of consolidation settlement after completion.…”

Numerical Analysis of Consolidation Settlement and Creep Deformation of Artificial Island Revetment Structure in a Large-Scale Marine Reclamation Land Project

“…Based on the spread of study of soft soil settlement problem of finite method, Folque presented a consolidation model of unsaturated soil considering rheological question and got the solution of constitutive equation of model [5,8]. Tang Bin et al [9] adopted finite producer to analyze consolidation of soft soil foundation based on rheological characters; Mamoru Mimura et al [6] studied number one runway of Kansai International Airport and contrasted local actual monitoring value with finite numerical calculation value of consolidation settlement post construction. The two results are al-most similar.…”
