AASHTO LRFD Drilled Shaft Analysis Tool

Project description

PyPile: AASHTO LRFD Drilled Shaft Analysis

Python Version License Standard

PyPile 是一个模块化、面向对象的 Python 库,专门用于按照 AASHTO LRFD Bridge Design Specifications (9th Edition)FHWA-NHI-10-016 标准计算钻孔灌注桩(Drilled Shafts / Bored Piles)的轴向承载力。

该项目旨在为岩土工程师提供一个透明、可扩展且自动化的计算工具,替代繁琐且容易出错的 Excel 表格。

🚀 主要特性 (Key Features)

  • 规范合规 (Code Compliance): 严格遵循 AASHTO LRFD 规范,内置抗力系数 ($\varphi$) 和极限阻力限制 (Limits)。
  • 多地层处理 (Multi-Layer Stratigraphy): 支持复杂的“上软下硬”地层、夹层以及地下水位影响。
  • 自动化参数关联 (Auto-Correlations):
    • 自动将野外 SPT $N$ 值修正为 $N_{60}$。
    • 基于 $N$ 值自动估算土体重度 ($\gamma$)、内摩擦角 ($\phi'$) 和不排水抗剪强度 ($S_u$)。
  • 高级算法 (Advanced Solvers):
    • 黏土 (Clay): $\alpha$-Method (Total Stress).
    • 砂土 (Sand): $\beta$-Method (Effective Stress).
    • 中间岩土材料 (IGM): 针对 $N > 50$ 的极密实土层或软岩的特殊处理逻辑。
  • 模块化架构: 易于扩展新的计算方法或集成到更大的 Web/Desktop 应用中。

📦 安装 (Installation)

目前 PyPile 处于开发阶段,建议通过克隆仓库进行本地安装:

git clone [https://github.com/yourusername/pypile.git](https://github.com/yourusername/pypile.git)
cd pypile

# (可选) 创建虚拟环境
python -m venv venv
source venv/bin/activate  # Windows: venv\Scripts\activate

# 安装依赖 (如果有)
pip install -r requirements.txt
