Reinforcing method for earthen archaeological site undercut area
The invention provides a reinforcing method for an earthen archaeological site undercut area, belongs to the technical field of earthen archaeological site repairing and reinforcing, and solves the problems of shrinkage and settlement of a foundation, dry shrinkage and consolidation of a rammed complement and the like in an existing method for supporting and reinforcing the earthen archaeological site undercut area, so that cracks with different sizes are generated on an interface of the rammed complement and a body after reinforcement. The method comprises the following specific steps: clearing deficiency; measuring an undercut area; interface lapping is carried out; foundation replacement; formwork erecting and ramming; mold removal and rectification; wherein three lap joint modes of anchor rod lap joint, notch groove lap joint and anchor rod and notch groove lap joint are adopted for interface lap joint, and a composite foundation composed of a rubble cushion layer and a modified soil cushion layer is adopted for replacing an original foundation. When the method is adopted for ramming repair of the earthen ruin undercut area, occurrence and development of ramming complement-body interface cracks caused by foundation settlement and ramming complement dry shrinkage consolidation can be effectively inhibited, the compatibility and durability of a reinforcing body and a body are improved, and a good reinforcing effect is achieved.
本发明提出了一种用于土遗址掏蚀区的加固方法，属于土遗址修复加固技术领域，解决目前对土遗址掏蚀区进行支顶加固的方法存在地基的收缩沉降、夯补体自身的干缩固结等问题，使得加固后夯补体和本体交界面产生大小不一的裂缝。本发明的具体步骤为：清虚；掏蚀区测量；界面搭接；基础置换；立模夯筑；拆模整饬；其中界面搭接采用锚杆搭接、刻槽搭接和锚杆+刻槽搭接三种搭接模式，采用片石类垫层和改性土垫层所组成的复合地基对原有基础进行置换。采用本发明的方法对土遗址掏蚀区进行夯补修复，可以有效抑制地基沉降以及夯补体干缩固结所引起的夯补体‑本体界面裂缝的发生和开展，提高了加固体与本体的兼容性和持久性，获得了良好的加固效果。
