タイトル（英）：	SASEISIMIC DESIGN BY GROUND IMPROVEMENT FOR DAMAGE EXAMPLES OF SOIL-PILE FOUNDATION SYSTEM
抄録（英）：	This paper presents an evaluating method for responses of soil-pile foundation-super structure system taking into consideration liquefaction of ground layer and ground improvement by the compacting method. Proposed method uses the computer program NUW2 for 2D effective stress analysis and WAP3 for simulation of sand compaction pile method. Numerical computations are performed for the initial and improved ground models of damage examples in 1995 Hyougoken-nanbu Earthquake. Results of responses of ground layers and pile foundations evaluate the performance of ground improvement for preventing liquefaction and damage of piles. Main conclusion is that the proposed evaluating method is effective for reducing pile stress under allowable limit in sandy ground layer but ground improvement may be difficult to prevent pile failure in clayey ground.
