Arched abutment structure and construction method thereof
The invention discloses an arched bridge abutment structure and a construction method thereof. The arched bridge abutment structure comprises two groups of pile foundations, the two bearing platforms are arranged in one-to-one correspondence with the two sets of pile foundations, one ends of the pile foundations are connected with the bearing platforms, the bearing platforms are provided with ballasting plates, the ballasting plates protrude out of the bearing platforms, and the ballasting plates are used for filling soil behind the bearing platforms; the platform body comprises a platform body and an arch rib, the platform body is connected with the bearing platforms, the platform body and the ballasting plate form an L-shaped structure, the two ends of the arch rib are connected to the two bearing platforms respectively, and the rise span ratio of the arch rib ranges from 0.222 to 0.125; and the retaining wall is connected with the arch rib and is used for filling a cavity below the arch rib so as to prevent a soil body behind the abutment from sliding off. According to the invention, the arch-shaped abutment body is arranged and straddled on the existing subway line, so that the construction of the abutment can be carried out under the condition that the operation of the existing subway is not influenced; the ballasting plate and the abutment body form an L-shaped structure, so that the gravity part of filling soil behind the abutment can be partially converted into resistance for resisting the lateral soil pressure of the filling soil, and the stability of the abutment is improved.
本发明公开了一种拱形桥台结构及其施工方法，拱形桥台结构包括两组桩基；两个承台，两个承台分别与两组桩基一一对应设置，桩基的一端与承台连接，承台设有压重板，压重板凸出于承台，压重板用于承载台后填土；台身，其包括台身本体和拱肋，台身本体与承台连接并与压重板构成“L”形结构，拱肋的两端分别连接至两个承台，拱肋的矢跨比取值范围为0.222～0.125；挡墙，其与拱肋连接，用于填补拱肋下的空洞以阻挡台后土体滑落。本发明通过设置拱形台身，且使其骑跨在现有地铁线路上，从而能够在不影响现有地铁运营的情况下进行桥台的建设；压重板和台身构成“L”形结构，从而能够将台后填土的重力部分转化为抵抗填土侧向土压力的抵抗力，提升桥台的稳定性。
