DIAGONAL SUPPORT PILE TYPE SHEET PILE QUAY
To provide a diagonal support pile type sheet pile quay capable of demonstrating great earthquake resistance even in the event of a huge earthquake while securing economic superiority by suppressing unnecessary increases in construction costs compared to other pile quays, and the like.SOLUTION: A diagonal support pile type sheet pile quay 100 that is formed on the boundary between the sea and the land includes a sheet pile wall 10 along the coastal area and only a push-in pile 12 with a stay pile that is tied to the sheet pile wall 10 by a tie material 11 on the land side of the sheet pile wall 10. The lower end 12a of the push-in pile 12 is embedded longer than the diameter of the push-in pile in an engineering foundation G2. The lower limit of the length of the tie material 11 is set to the larger one of the values calculated by [Equation 1] or [Equation 2] below to bear with level 2 seismic motion. Lmin(H, α)=H×tanα+a [Equation 1], Lmin(h)=2.70×h-23.60 [Equation 2]SELECTED DRAWING: Figure 1
【課題】工費の不要な増加を抑制して控え組杭式矢板岸壁等と比較して経済優位性を確保しながらも、巨大地震発生時においても大きな耐震性を発揮する。【解決手段】海と陸との境に設けられる斜め控え支持杭式矢板岸壁１００であって、臨海部に沿って矢板壁１０を備え、矢板壁１０の陸側においてタイ材１１により矢板壁１０と繋がれた控え杭として、押し込み杭１２のみを備え、押し込み杭１２の下端部１２ａが押し込み杭の直径長以上、工学的基盤Ｇ２に根入れされ、タイ材１１の長さの下限値は、以下の〔式１〕または〔式２〕により算出される値のうち大きい方の値が設定され、レベル２地震動に対応可能とした。Ｌｍｉｎ（Ｈ、α）＝Ｈ×ｔａｎα＋ａ〔式１〕、Ｌｍｉｎ（ｈ）＝２．７０×ｈ－２３．６０〔式２〕【選択図】図１
