Simulation test platform for shallow-buried subsea tunnel in chlorine salt erosion environment and construction method of platform
The invention discloses a simulation test platform for a shallow-buried subsea tunnel in a chlorine salt erosion environment and a construction method of the platform. The method comprises the following steps of taking a field prototype tunnel as a reference, and modeling and constructing an indoor ground according to a similar scale ratio to build a tunnel lining structure model; transversely modeling at the front end and the rear end of the tunnel lining structure model and by crossing the tunnel lining structure model left and right, and pouring the model box transverse vertical plates; longitudinally modeling at the left and right ends of the front and rear transverse vertical plates, pouring the model box longitudinal vertical plates, and enclosing the longitudinal vertical plates and the transverse vertical plates to form a model box with an open upper end; filling a rock-soil body similar material which is similar to the geological environment above the field prototype tunnel in the model box and above the tunnel lining structure model; taking a seawater sample of a sea area where the field prototype tunnel is located, and submerging the rock-soil body similar material. By adopting the construction method, the simulation test platform for the shallow-buried subsea tunnel in the chlorine salt erosion environment is built indoors, so that the corrosion environment of the tunnel lining is completely matched with that of an engineering site.
本发明公开了一种氯盐侵蚀环境浅埋海底隧道模拟试验平台及其施工方法，如下：以现场原型隧道为基准，按相似缩尺比在室内地面立模浇筑施作隧道衬砌结构模型；在隧道衬砌结构模型的前后两端，且均左右跨越隧道衬砌结构模型横向立模，浇筑模型箱横向立板；在前后两个横向立板的左右端均纵向立模，浇筑模型箱纵向立板，纵向立板和横向立板围成一上端敞口的模型箱；在模型箱内，且位于隧道衬砌结构模型上方填充与现场原型隧道上方地质环境相似的岩土体相似材料；取现场原型隧道所在海域海水试样，淹没岩土体相似材料。采用该施工方法在室内建立了氯盐侵蚀环境浅埋海底隧道模拟试验平台，使隧道衬砌的腐蚀环境完全与工程现场吻合。
