More Information
Summary:The invention discloses a construction method for a shallow-buried partial-pressed non-symmetrical support arch. The construction method comprises the steps of water-intercepting gutter constructing, non-symmetrical support arch foundation constructing, non-symmetrical support arch constructing and cave-top backfilling. According to the construction method for the shallow-buried partial-pressed non-symmetrical support arch, the construction method is simple, the construction steps are closely linked, and the design of arranged positions, structures and sizes of the tunnel support arch and pile foundations are reasonable; the construction method has the advantages that construction is convenient and fast; and the effect of partial-pressure resistance is good, risks brought by shallow-depth and partial pressure of a tunnel to safety of railway operation can be reduced effectively. 本发明公开了种浅埋偏压不对称式护拱施工方法，包括截水天沟施工、不对称式护拱基础施工、不对称式护拱施工和洞顶回填。本发明的施工方法简单，施工各步骤衔接紧密，隧道护拱及桩基布置位置、结构与尺寸设计合理；采用本发明施工方法施工具有施工便捷，施工速度迅速的优点；本发明的抗
