Determination method of solidified soil anti-scouring structure for single-pile foundation
The invention discloses a method for determining a solidified soil anti-scouring structure for a single pile foundation. The method comprises the steps that firstly, the fluctuation and ebb tide time and the flow velocity change rule within 7 days of the construction period are determined; step 2, proportioning the solidified soil on site and carrying out an anti-scouring test to obtain a curve of the change of the anti-scouring critical flow velocity of the solidified soil along with the mixing amount of the curing agent in different states; 3, determining the strength and proportion of the solidified soil according to the construction period flow velocity and the use period flow velocity; 4, the sensitivity of the single-pile foundation to scouring is judged in combination with the geological conditions and the scouring evolution condition; 5, determining an existing scour range for the foundation with the scour phenomenon on the periphery; for the foundation which is not scoured, the solidified soil protection range is calculated and determined; step 6, determining main process equipment; 7, evaluating the anti-scouring structure through a mathematical model test or a physical model test; and 8, finally obtaining the optimized solidified soil anti-scouring structure. According to the invention, a safe and economic balanced optimization scheme can be obtained.
本发明公开了一种用于单桩基础的固化土防冲刷结构的确定方法，包括：步骤一，确定施工期7天内涨落潮时间和流速变化规律；步骤二，现场进行固化土配比并进行抗冲刷试验，得到不同状态下固化土抗冲刷临界流速随固化剂掺量变化曲线；步骤三，根据施工期流速和使用期流速确定固化土强度及配比；步骤四，结合地质条件和冲刷演变情况，判断单桩基础对冲刷的敏感性；步骤五，对周边已出现冲刷现象的基础，确定已有冲刷范围；对于未出现冲刷的基础，计算确定固化土防护范围；步骤六，确定主要工艺装备；步骤七，通过数学模型试验或物理模型试验对防冲刷结构进行评估；步骤八，最终得到优化的固化土防冲刷结构。本发明能得到安全与经济均衡的优化方案。
