Suspension bridge tunnel type anchorage and construction method
The invention relates to the technical field of tunnel type anchorage, in particular to a suspension bridge tunnel type anchorage and a construction method, the anchorage structure comprises at least two tunnel anchor units, and the tunnel anchor units are communicated with each other through anchor plug bodies. According to the scheme, the at least two tunnel anchor units are arranged and communicate with one another through the anchor plug bodies, so that the independent tunnel anchor units form a whole, the resistance of the rock-soil body in the area defined by the anchor plug bodies and the tunnel anchor units on the two sides can be fully utilized, the stress of the rock-soil body in a wider range can be transferred, and the stress of the rock-soil body in the area defined by the anchor plug bodies and the tunnel anchor units on the two sides can be reduced. And then soil bodies in the upper and lower ranges of the rock-soil bodies are further transferred to participate in stress through the shear resistance effect of the rock-soil bodies, the anti-pulling safety coefficient of the tunnel anchor is greatly improved, and therefore the construction form of the tunnel type anchorage is not high in geological condition requirement, high in adaptive capacity and beneficial to meeting the structural stress requirement.
本发明涉及隧道式锚碇技术领域，具体涉及一种悬索桥隧道式锚碇及施工方法，锚碇结构包括至少两个隧道锚单元，所述隧道锚单元之间通过锚塞体相互连通。在本方案中，通过设置至少两个隧道锚单元并将隧道锚单元间通过锚塞体相互连通，使独立的各隧道锚单元之间形成整体，能够充分利用锚塞体与两侧隧道锚单元所围成区域的岩土体的抗力，调动更广范围的岩土体受力，然后进一步通过岩土体的抗剪作用调动其上下范围的土体参与受力，大大提高了隧道锚的抗拔安全系数，因此这种隧道式锚碇的构造形式对地质条件要求不高，适应能力较强，利于满足结构受力需求。
