摘要
结合工程项目实践经验,在场地岩溶强发育地段同时抗浮设防水位较高的情况下,采取多种措施解决抗浮问题。在抗浮设计中围绕整体稳定和局部稳定,充分考虑结构自重后,通过抗拔桩、抗浮锚杆及加厚地下室底板等措施,利用有限元计算模型进行抗浮设计与分析。结合相关设计规范的要求,确定了抗拔桩和抗浮锚杆的基本构造及锚固长度。实践表明:防水板+抗浮锚杆或是防水板+抗浮桩的布置方式,底板变形均能满足设计要求,根据工程特点、地质条件、场地条件和环境等因素,采取不同效果的抗浮治理措施,达到安全适用、经济合理、方便施工的效果,是本案例抗浮设计的基本原则。
Based on the practical experience of engineering projects, this paper takes various measures to solve the problem of anti-floating in the case of high anti-floating water level in the area with strong karst development.The anti-floating design focuses on the overall stability and local stability.After fully considering the dead weight of the structure, the measures of anti-floating pile, anti-floating bolt and thickening basement bottom plate are adopted, and the anti-floating design and analysis are carried out based on finite element models.According to the requirements of relevant design specifications, the basic structure and the anchoring length of the anti-floating pile and the anti-floating bolt are determined.Practice shows that the deformation of the bottom plate can meet the design requirements by using waterproof plate + anti-floating bolt or waterproof plate + anti-floating pile.According to the engineering characteristics, geological conditions, site conditions and environmental factors, anti-floating control measures with different effects are adopted to achieve safe, applicable, economic and convenient construction effect.
