ASEISMIC EMBANKMENT STRUCTURE, AND CONSTRUCTION METHOD OF ASEISMIC EMBANKMENT
PROBLEM TO BE SOLVED: To provide an aseismic embankment structure and a construction method for an aseismic embankment that may be realized through simple construction processes and effectively enhance seismic stability of the embankment.SOLUTION: An aseismic embankment structure 100 includes a long member 20 having an end 20a held in a block 1 and integrated with a retaining wall 10, and a covered member 30 fixed on the end 20a of the long member 20 protruding on a wall surface of the retaining wall 10, the cover member being integrated with the retaining wall 10. Therefore, the aseismic embankment structure suppresses collapsing of the retaining wall 10 with the long member 20 that functions as an anchor and suppresses partial squeezing out of the block 1 by the covered member 30 covering the wall surface of the retaining wall 10 when earth pressure of an embankment 50 is exerted on the retaining wall 10, and therefore prevents damage to the retaining wall 10. With the aseismic embankment structure 100 that includes the hard-to-be-damaged retaining wall 10, seismic stability of the embankment 50 may be preferably enhanced. Also, the aseismic embankment structure may be constructed through simpler construction processes compared to a construction method in which the retaining wall is built by casting concrete at a site.SELECTED DRAWING: Figure 1
【課題】簡便な施工で構築でき、好適に盛土の耐震性を高めることができる耐震性盛土構造及び耐震性盛土の構築方法を実現する。【解決手段】耐震性盛土構造１００は、一端部２０ａがブロック１に挟み込まれて擁壁１０と一体化された長尺部材２０と、擁壁１０の壁面に突き出ている長尺部材２０の一端部２０ａに固定されて擁壁１０と一体化された被覆部材３０とを備えているので、擁壁１０に盛土５０の土圧が作用した際、アンカーとして機能する長尺部材２０によって擁壁１０が倒壊するのを抑制するとともに、擁壁１０の壁面を覆う被覆部材３０によってブロック１が部分的に押し出されてしまうのを抑制することができ、擁壁１０が損傷するのを防ぐことができる。このような損傷し難い擁壁１０を備えている耐震性盛土構造１００であれば、好適に盛土５０の耐震性を高めることができる。また、施工現場で擁壁を場所打ちして構築することに比べて簡便に構築できる。【選択図】図１
