• SHAKING TABLE TEST ON SEISMIC BEHAVIOR OF CAISSON TYPE QUAY-WALL IN APPLICATION OF CEMENT-MIXING METHOD

抄録

In order to investigate the effect of cement-mixing for reducing the seismic damage of caisson type quay-wall, a series of shaking table tests in 1g gravitational field were performed in terms of the shear strength and the improvement range of cement-mixing. The main conclusions obtained form this study are as follows; 1) Cement-mixing behind caisson type quay-wall is effective for reducing the seismic damage of caisson type quay-wall. 2) For cement-mixed ground with a large shear strength, the seismic behavior of quay-wall sympathizes with cement-mixed ground as if cement-mixed ground and quay-wall are a combined structure. Consequently, the seismic earth pressure from liquefied ground is absorbed by cement-treated ground reducing the seismic earth pressure to quay-wall. 3) A formula to evaluate the sliding safety of caisson type quay-wall with cement-mixing was proposed considering the cohesive component of shear strength in cement-mixed ground. Based on the proposed formula, improvement range of cement-mixing can be reduced from a conventional range in current design code for cement-mixing.
