ANALYTICAL STUDY ON SEISMIC PERFORMANCE OF SHEET PILE AT THE CORNERS OF BULKHEADS OF WASTE DISPOSAL SITE

Abstract

Due to the technical difficulties, an analysis has been made only on two-dimensional planes in the design of a sealing structure. As a result, no verification has been made on the seismic performance at the corners of bulkheads. With a parallel computation method, it models sealing sheet piles and bulkheads meeting at right angle simultaneously, and to identify the behavior of corners of bulkheads and the stress state occurred on the sealing sheet piles when subjected to the level II earthquake. This study showed the inplane shear stress of the sealing sheet piles at the corner areas being at the most critical state, as well as the sealing performance of the sheet piles.
