(ZH) 超大变断面隧道支护结构
Abstract: front page image
(EN)Disclosed is a support structure for a tunnel having ultra-large variable section, the support structure comprising, along an annular shape of the tunnel, a vault (11) at a top portion, an inverted arch (12) at a bottom portion, side walls (13) and pilot tunnels outside of the side walls (13) at two sides, and also comprising, along a radial direction of the tunnel, a secondary lining (2) at an inner layer; pilot tunnel primary supports (42) are disposed outside the secondary linings of the two side walls (13); a boot-type large wall footing (41) is cast between the pilot tunnel primary support (42) and the secondary lining at the two side walls; a primary support (31) is disposed, along the radial direction of the tunnel, on an outer surface of a secondary lining of the vault (11) and a secondary lining (21) of the inverted arch; an inner layer primary support (32) is disposed between the secondary lining and the primary support (31) of the vault; the primary support (31) of the vault and the inner layer primary support (32) are both supported by the boot-type large wall footing (41); and the primary support of the inverted arch is supported by the pilot tunnel primary support (42). The support structure can better overcome insufficient bearing capacity of a soft foundation, and provide a stable foundation for the upper portion of the structure.
(FR)L'invention concerne une structure de support pour un tunnel à ultra-grande section variable, la structure de support comprenant, le long d'une forme annulaire du tunnel, une voûte (11) au niveau d'une partie supérieure, un arc inversé (12) au niveau d'une partie inférieure, des parois latérales (13) et des tunnels pilotes à l'extérieur des parois latérales (13) au niveau de deux côtés, et comprenant également, le long d'une direction radiale du tunnel, une garniture secondaire (2) au niveau d'une couche intérieure ; des supports primaires (42) de tunnel pilote sont disposés à l'extérieur des garnitures secondaires des deux parois latérales (13) ; une semelle de paroi (41) de la largeur d'une botte est coulée entre le support primaire (42) de tunnel pilote et la garniture secondaire au niveau de deux parois latérales ; un support primaire (31) est disposé, le long de la direction radiale du tunnel, sur une surface extérieure d'une garniture secondaire de la voûte (11) et d'un revêtement secondaire (21) de l'arc inversé ; un support primaire (32) de couche intérieure est disposé entre la garniture secondaire et le support primaire (31) de la voûte ; le support primaire (31) de la voûte et le support primaire (32) de la couche intérieure sont tous les deux supportés par la semelle de paroi (41) de la largeur d'une botte ; et le support primaire de l'arc inversé est supporté par le support primaire (42) du tunnel pilote. La structure de support peut mieux surmonter la capacité d'appui insuffisante d'une fondation souple, et fournir une fondation stable à la partie supérieure de la structure.
