【発明が解決しようとする課題】ところで、地下構造体
50,51はまわりを土４で囲まれているので、土に対面す
る側壁は土圧を受けることになる。By the way, an underground structure
Since 50 and 51 are surrounded by soil 4, the side wall facing the soil is subjected to earth pressure.
【０００５】天井部を有する地下構造体50の場合、側壁
上部は天井部材、側壁下部は床部材でそれぞれ支持され

に対する補強部材として機能することになる。In the case of the underground structure 50 having a ceiling portion, since the upper side wall is supported by the ceiling member and the lower side wall is supported by the floor member, the ceiling member and the floor member each function as a reinforcing member against earth pressure. It will be.
【０００６】しかし、天井部が開口する地下構造体51の
場合、図３に示すように、側壁上部を支持する部材がな
く、このため側壁上部は土圧により点線のようなへこみ
が生じるおそれがある。However, in the case of the underground structure 51 having an open ceiling, as shown in FIG. 3, there is no member for supporting the upper portion of the side wall, so that the upper portion of the side wall may be dented as shown by the dotted line due to earth pressure. is there.
【０００７】このような問題に対し、地下構造体の室内

不要な部材の配置はできるだけ避け、有効面積をなるべ
く拡大させるのが好ましく、このため室内に支持部材を
配置する構成はそのような趣旨に合致しない。In order to solve such a problem, a structure in which a supporting member is provided in the room of the underground structure is conceivable. However, as described above, the underground structure having an opening secures ventilation and daylight and a staircase portion. From the purpose of forming
It is preferable to avoid disposing unnecessary members as much as possible and to expand the effective area as much as possible. Therefore, the structure in which the supporting member is arranged in the room does not meet such a purpose.
【０００８】本発明は、以上のような問題に鑑み創案さ
れたもので、なるべく地下構造体の室内には補強部材を
配置させずに、土に対面する側壁の補強が図れる地下構
造体の耐土圧構造を提供しようとするものである。The present invention was devised in view of the above problems, and as much as possible, the soil resistance of an underground structure which can reinforce the side wall facing the soil without disposing a reinforcing member in the room of the underground structure. It is intended to provide a pressure structure.

【課題を解決するための手段】このため、本発明に係る
開口部を有する地下構造体の耐土圧構造は、少なくとも
一の側壁が土に対面し、かつ天井部が開口する地下構造
体において、その幅方向端部であってかつその長方向に
沿って張出部が形成される長尺部材を、その張出部が、
土に対面する側壁から外方に飛び出すように、前記側壁
上部の辺長に亘って固着したことを特徴とする。Therefore, an earth pressure resistant structure for an underground structure having an opening according to the present invention is an underground structure in which at least one side wall faces soil and a ceiling part is open, A long member that is an end portion in the width direction and in which a protruding portion is formed along the lengthwise direction is
It is characterized in that it is fixed over the side length of the upper part of the side wall so as to project outward from the side wall facing the soil.
【００１０】ここで、前記長尺部材の形状、すなわちそ

は、いずれの面も張出部といえるような、例えば断面く
の字状のような形状（形鋼で言えば等辺山形鋼）も含む
ものとする。Here, the shape of the elongated member, that is, the shape of the end portion in the width direction and the projecting portion formed along the length direction thereof is, for example, I-shaped in cross section or H-shaped, L-shape, T-shape, and U-shape are possible. Further, in the present invention, a shape having a V-shaped cross section (equilateral angle steel in the case of shaped steel), for example, in which any surface can be referred to as an overhang portion, is also included.
【００１１】また、前記長尺部材は補強部材であること

側壁が部分的にへこむようなことがなくなる。As described above, the earth pressure as shown by the arrow in FIG. 3 is applied to the side wall facing the soil, but the overhanging portion of the long member fixed to the upper portion of the side wall receives the earth pressure. . In particular, since the overhanging portion is located along the side length of the upper portion of the side wall, the earth pressure applied to the upper portion of the side wall is received over the length of the long member through the overhanging portion. As a result,
The side wall is not partially dented.

も快適な空間を演出しやすくなる。At least the projecting portion of the elongated member is located on the outer side of the side wall. Therefore, since all of the long members which are the reinforcing members are not located in the room of the underground structure, the effective area in the room is increased. Particularly, if most of the long members are projected to the outside of the side wall, the effective area in the room can be maximized. Of course, when the structure having an opening is used as a so-called dry area, the area for ensuring ventilation and daylight is large, and it is easy to produce a comfortable space for decoration.
