Horizon: CPT-based liquefaction risk assessment and decision software
收藏资源简介:
Horizon is windows-executable software for analyzing the occurence, consequence, mitigation, and economics of seismically-induced soil liquefaction via CPT sensing and models. Salient features include: (1) CPT processing: Inverse filtering and interface correction; CPT sensor alignment via statistical cross-correlation. (2) Six triggering models; Four free-field manifestation models; Shallow-foundation fragility and vulnerability models. (3) Seamless integration with USGS probabilistic seismic hazard analysis (PSHA) framework; Compute return periods of free-field manifestation, foundation damage, and economic loss. (4) Cost-benefit analytics for deciding whether/how to mitigate risks; Quantify value of planned or constructed mitigation.
Horizon是一款可在Windows环境下运行的专业软件,旨在通过静力触探(CPT)传感技术与相关模型,分析地震诱发土壤液化的发生过程、灾害后果、减灾措施及经济影响。其核心显著特性包括: (1) CPT处理模块:涵盖反滤波与界面校正,可通过统计互相关实现CPT传感器的精准校准。 (2) 内置六种地震液化触发模型、四种自由场液化表现模型,以及浅基础破坏概率与易损性模型。 (3) 可与美国地质调查局(United States Geological Survey,USGS)概率地震危险性分析(Probabilistic Seismic Hazard Analysis,PSHA)框架实现无缝集成,能够计算自由场液化表现、基础破坏与经济损失的重现期。 (4) 支持面向风险减灾决策的成本效益分析,可量化规划中或已建成的减灾措施的实施价值。
