High-Resolution Near-Surface Soil Model Developed for Site Response Analysis in Alameda, CA.

This project describes the development of a high-resolution near-surface soil model for the city of Alemda, CA using SCPT data and local geotechnical reports. This study focuses on the city of Alameda to illustrate the benefits of modeling near-surface soil characteristics to obtain high-fidelity site response analyses input parameters and can be used as a framework for using SCPT data and borehole reports to generate a probabilistic sub-surface soil model. This work can benefit the earthquake engineering community, particularly those involved in seismic ground shaking and liquefaction research.

本项目利用静力触探试验（Static Cone Penetration Test, SCPT）数据与当地岩土工程报告，为加利福尼亚州阿尔门达市构建了高分辨率近地表土壤模型。本研究以阿尔门达市为研究对象，旨在阐明通过近地表土壤特性建模获取高精度场地响应分析输入参数的优势，同时可作为利用SCPT数据与钻孔报告生成概率地下土壤模型的通用框架。该研究成果可惠及地震工程领域，尤其对开展地震地面震动与土壤液化研究的人员具有重要参考价值。
