Method for treating karst cave in argillaceous limestone area
The invention relates to the technical field of civil engineering, and discloses an argillaceous limestone region karst cave treatment method which comprises the following steps: step A, carrying out geological investigation, including drilling investigation, geological radar detection and standard penetration test, so as to determine the position, shape, size and geological layer characteristics of a karst cave; and B, a micro-pile arrangement scheme is designed, the pile diameter, the pile length, the pile distance and the pile type are determined, the single-pile bearing capacity and the total pile foundation number are calculated according to the building load, and the calculation formula of the single-pile bearing capacity is shown in the specification. By arranging the micro piles in the karst cave area and injecting the self-healing material slurry, high stability of the foundation is achieved, the bearing capacity and the anti-settling capacity are enhanced, and long-term safety and durability of a building are guaranteed; by adopting the self-healing material and strict construction detection measures, foundation cracks are automatically repaired, the service life of the structure is prolonged, and meanwhile the safety and reliability of foundation reinforcement engineering are improved.
本发明涉及土木工程技术领域，公开了一种泥质灰岩地区溶洞处理方法，包括以下步骤：步骤A：进行地质勘察，包括钻孔勘察、地质雷达探测和标准贯入试验，以确定溶洞的位置、形状、大小和地质层特性；步骤B：设计微桩布置方案，确定桩径、桩长、桩距及桩型，并根据建筑荷载计算单桩承载力和总桩基数量，其中单桩承载力的计算公式为。通过在溶洞区域布设微桩并注入自愈合材料浆液，实现了地基的高稳定性、增强了承载能力和抗沉降能力，确保了建筑物的长期安全性和耐久性；通过采用自愈合材料及严格的施工检测措施，实现了自动修复地基裂缝、延长了结构使用寿命，同时提高了地基加固工程的安全性和可靠性。
