Design method of large-diameter high-temperature molten salt storage tank foundation in shallow bedrock area
The invention discloses a design method of a large-diameter high-temperature molten salt storage tank foundation in a shallow bedrock region. The foundation mainly comprises the following construction steps from bottom to top: replacing and filling a graded gravel cushion layer, burying a deep ventilation pipe at the top of a gravel top layer, mounting a steel ring wall, filling the steel ring wall with artificial ceramsite soil, burying a temperature detector in the ceramsite soil, and making a slope on a ceramsite soil top surface sand layer. The first state and the second state are comprehensively considered in the design of the steel ring wall. In the first state, a steel ring wall circumferential stress calculation formula is deduced according to stress analysis of the steel ring wall under the load of the upper storage tank. In the second state, a calculation model is established according to heat conduction analysis of the steel ring wall under soil constraint, and then a steel ring wall stress calculation result is obtained. The safe and reliable high-temperature molten salt storage tank foundation is designed by comprehensively considering the two states, the construction period of the designed high-temperature molten salt storage tank foundation is short, and quality control is easy.
本发明公开了一种基岩较浅地区的大直径高温熔盐储罐基础的设计方法，基础从下至上按施工步骤主要构成有：换填级配砂石垫层、砂石顶层顶部埋深通风管、钢环墙条形基础、安装钢环墙、钢环墙内填充人工陶粒土、陶粒土内埋设温度检测计，陶粒土顶面砂层找坡。其中钢环墙设计综合考虑了状态一和状态二。状态一根据钢环墙在上部储罐荷载下的受力分析推导出钢环墙环向应力计算公式。状态二根据钢环墙在土体约束下的热传导分析建立计算模型进而得出钢环墙应力计算结果。综合考虑以上两种状态设计出安全可靠的高温熔盐储罐基础，且设计出的高温熔盐储罐基础施工周期短、质量控制较容易。
