摘要

本研究的目的是将深开挖行为预测模型应用于岩土工程领域,以建立砾石层的局部土壤参数。包括PLAXIS和SoilWorks在内的通用软件工具被广泛使用。收集台湾新店地区与砾石层有关的深基坑工程监测资料。在背景分析中,使用了挡土墙的变形,而不是深基坑分析中通常使用的参数。这是为了在对新店区地层或类似地层进行数值模拟分析时,为输入参数提供理想的范围建议。评估结果表明,当将第五层砾石设置为SPT-N=100时,PLAXIS建议土壤弹性模量范围为7840 N至9800 N/平方米(kN/m2),而SoilWorks建议土壤弹性模数范围为2450 N至3430 N/平米(kg/m2)。这些范围允许对最终开挖阶段的最大墙体变形进行合理估计。根据研究结果,建议工程师在台湾新店地区或类似地层的砾石层中进行开挖分析时,在选择不同软件程序的土壤弹性模量时,应参考上述推荐范围。这将提高最终开挖阶段变形预测的准确性。

Establishment of Localized Utilization Parameters for Numerical Simulation Analysis Applied to Deep Excavations
The aim of this study was to apply deep excavation behavior prediction models in the geotechnical field to establish localized soil parameters for gravel layers. Common software tools, including PLAXIS and SoilWorks, were used extensively. Monitoring data from deep excavation cases related to gravel layers in the Xindian area of Taiwan were collected. In the background analysis, the deformation of the retaining walls was used instead of parameters typically used in deep excavation analysis. This was performed to provide the ideal range recommendations for the input parameters when conducting a numerical simulation analysis of the Xindian District stratum or similar strata. The assessment results show that when setting the fifth layer of gravel to SPT-N = 100, PLAXIS suggested a soil elastic modulus range of 7840 N to 9800 N per square meter (kN/m2), while SoilWorks recommended a range of 2450 N to 3430 N per square meter (kN/m2). These ranges allow for a reasonable estimation of the maximum wall deformation during the final excavation stage. Based on the research findings, it is recommended that when conducting an excavation analysis in gravel layers in the Xindian area of Taiwan or in similar strata, engineers should refer to the abovementioned recommended ranges when selecting the soil elastic modulus for different software programs. This will enhance the accuracy of the deformation predictions during the final excavation stage.
