摘要
借助有限差分软件Tesseral对古建筑浅基础埋深进行了数值模拟分析,并分析了基础到旁孔距离、激振位置以及缺陷类型对基础埋深检测精度的影响,以便为实际工程提供参考。计算结果表明:对于砌体类浅基础埋深检测,为保证检测结果的精确度,基础边缘到旁孔的距离应尽量保持在0.5 m范围以内,且激振位置靠近旁孔。
The numerical simulation analysis of the buried depth of the shallow foundation of the ancient building is carried out by the finite difference software of Tesseral.The influence of the distance between the foundation and the side hole,the excitation position and the defect type on the detection accuracy is analyzed to provide a reference for the actual project.The calculation results show that the distance from the foundation edge to the side hole should be kept within 0.5 m as far as possible and the excitation position should be close to the side hole in order to ensure the accuracy of the detection results for the detection of the buried depth of masonry shallow foundation.
