점성토지반속 주열식 흙막이벽의 설계법 = A Design Method of Earth-Retaining Structure Constructed by a Row of Bored Piles in Cohesive Soils

다국어 초록 (Multilingual Abstract)

A design method is presented for the earth-retaining structure ccnslructtd by a row of bored Piles, which has such merits as low-vibration and low-noire during construction. And utility of the design method is investigated by performing a design example. First, theoretical rquations to estimate the resisting force of a row of earth-retaining was in cohesive soils are estabilished for grounds above and below bottom of excavation, reprctively. The characteristics of soils and the effect pile's interval can be considered logically in the theoretical equations. Then, the method for stability.analysis is presented for the earth-retaining piles by applying the theoretical equation of resisting forces on a row of piles. Finally, the design of earth-retaining piles is performed within the ranges which can satisfy the stabilities of both piles and soils. On investigation cf the sail-stability, the stability for bottom heave In cohesive soils is also investigated.
