Construction method of large bridge abutment in cavern in steep cliff section
The invention discloses a method for constructing a large bridge abutment in a hole in a steep cliff section, and relates to the field of construction of the large bridge abutment in the hole in the steep cliff section, the steep cliff section comprises an upper slope and a lower slope, and the method comprises the steps that a rigid frame bridge is constructed in the hole in the steep cliff section to form an upper structure; a uniform-section double-limb thin-wall pier and a bearing platform pile splicing foundation are constructed in the hole of the steep cliff section to form a lower structure; a pre-stressed concrete T-shaped beam is adopted, and an approach bridge upper structure is continuously formed after simple supporting; and an abutment cap is made on the lower structure in a pile-foundation-free mode, and the large abutment in the hole in the steep cliff section is formed. The upper structure and the lower structure are constructed in the hole in the steep cliff section, the large bridge abutment in the hole in the steep cliff section is formed in a pile-foundation-free mode, the construction steps are simplified, the construction difficulty of the large bridge abutment in the hole in the steep cliff section is reduced, and therefore the construction risk is reduced, the construction quality is guaranteed, and meanwhile the construction cost is reduced. The construction period is shortened, and the construction cost is reduced.
本发明公开了一种陡崖地段洞内大桥台施工方法，涉及陡崖地段洞内大桥台施工领域，所述陡崖地段包括上部斜坡和下部斜坡，所述方法包括：采用刚构桥在所述陡崖地段洞内施作形成上部结构；采用等截面双肢薄壁墩，承台接桩基础在所述陡崖地段洞内施作形成下部结构；采用预应力混凝土T梁，先简支后结构连续形成引桥上部结构；采用无桩基的方式，在所述下部结构做台帽，形成所述陡崖地段洞内大桥台。本发明通过分别在陡崖地段洞内施作形成上部结构和下部结构，并采用无桩基的方式，形成所述陡崖地段洞内大桥台，简化了施工步骤，降低了陡崖地段洞内大桥台的施工难度，从而降低了施工风险，在确保施工质量的同时，缩短了施工工期长，减少了工程造价高。
