According to the results of the mix-proportion tests, in the case of Nagoya port clay, when the water cement ratio was set to 1.2 and the water content was set to 60 to 100%, the strength of 10 MN/m 2 or more could be secured. In addition, in a production experi-ment of solidified soil block, a biaxial forced mixing mixer was used assuming construction on site. The constraint condition for producting a solidified soil block using this mixer was to secure fluidity for push-ing out the treated soil from the opening of the mixer. As a result of fixing the water cement ratio to 1.2 and increasing the water content, it was possible to produce a solidified soil block at the water content of about 107% and the strength of core samples taken from the solidified soil block was 10 MN/m 2 or more. 75","PeriodicalId":326143,"journal":{"name":"Journal of Japan Society of Civil Engineers, Ser.

In previous researches, the optimum ground improvement area was discussed through the numerical simulations at the excavation process. However, the seismic behavior of the tunnel was not clearly discussed. In this study, dynamic centrifugal model experiments under a gravi-tational acceleration of 50 G were conducted to clarify the dynamic behavior of the shallow tunnel with pre-ground improvement. In addition to the simple tunnel without ground improvement, two ground improvement patterns; (1) the ground around all the cross-sections of the tunnel was improved, and (2) the ground around the crown of the tunnel and the top section was improved, were investigated. From the re-sults, it is confirmed that when the entire ground around the tunnel was improved, shear deformation of the tunnel could be suppressed by the increment of the whole rigidity of surrounding ground. On the other hand, when the ground around the tunnel crown and the top section was improved, the response of the tunnel was amplified by the concentration of the weight at the upper part of the tunnel. Moreover, large cross-sectional forces were generated at the boundary between the improved and unimproved ground.","PeriodicalId":326143,"journal":{"name":"Journal of Japan Society of Civil Engineers, Ser.
