Anti-explosive ground impact protection measure for underground structure
The invention belongs to the technical field of underground structure protection engineering, and particularly relates to an anti-explosive ground impact protection measure for an underground structure. The buried protective layer is arranged on one side of the underground structure, and a gap is reserved between the buried protective layer and the underground structure; and the earth surface bullet shielding layer is arranged above the underground structure and the buried protective layer, and gaps are reserved between the earth surface bullet shielding layer and the top end of the underground structure and between the earth surface bullet shielding layer and the top end of the buried protective layer. Response and damage of the underground structure can be reduced, and safety of personnel and equipment in the underground structure is improved. When the buried protective layer is damaged under the action of explosive impact, the buried protective layer can be re-laid and backfilled with earthwork by excavating the groove, so that the replaceability of the buried protective layer is realized. The structure is simple, construction is convenient and fast, the manufacturing cost is low, damage to the underground structure under the explosive ground impact load can be effectively reduced, and high economic benefits and social benefits are achieved.
本发明属于地下结构防护工程技术领域，尤其涉及一种地下结构抗爆炸地冲击防护措施，包括地下结构；埋地防护层，埋地防护层设置在地下结构一侧，埋地防护层与地下结构之间留有间距；地表遮弹层，地表遮弹层设置在地下结构和埋地防护层上方，地表遮弹层与地下结构顶端、埋地防护层顶端之间留有间距。本发明能够降低地下结构的响应和损伤，提高地下结构内部人员和设备的安全性。当埋地防护层在爆炸地冲击作用下发生破坏，可通过开挖沟槽重新铺设并回填土方，以实现埋地防护层的可更换性。本发明结构简单、施工便捷、造价低廉，能够有效降低地下结构在爆炸地冲击荷载下的损伤，具有较强的经济效益和社会效益。
