基樁在互層土承載力之自動化程式設計

Abstract

隨著城市化的快速發展，基礎設施建設的需求不斷增長，對基樁設計的效率與準確性提出了更高要求。然而，傳統的手算方法因計算過程繁瑣、耗時且易受人為因素影響，逐漸無法滿足現代工程的需求，這也推動了自動化設計工具的開發與應用。本研究旨在開發一套自動化程式，用於計算基樁在互層與單層土壤中的承載力，提升設計效率與精確度。該程式整合了多種土壤模型與設計標準，考慮不同土層的特性與基樁的條件進行分析，能有效處理不同土壤結構下的樁底承載力和樁身摩擦力，從而準確計算基樁的極限承載力。 使用者通過操作介面輸入包括土壤參數、基樁尺寸與形狀等相關設計數據，程式將根據靜力學公式與摩擦力分析模型，利用多種分析方法（如API法、Meyerhof法等）進行承載力計算，並生成清晰的結果圖表和數據，展示承載力隨深度變化的趨勢。同時，為確保程式計算的準確性與可靠性，透過自動化程式及手算結果、APILE軟體的結果進行比對，驗證程式的準確性與可靠性。結果顯示，該程式能夠在合理誤差範圍內提供精確的承載力計算結果，並在不同的土壤和基樁條件下保持穩定性與一致性。

With the rapid development of urbanization, the growing demand for infrastructure construction has placed higher requirements on the efficiency and accuracy of pile foundation design. However, traditional manual calculation methods, characterized by cumbersome processes, time consumption, and susceptibility to human error, are gradually unable to meet the needs of modern engineering. This has driven the development and application of automated design tools.

This study aims to develop an automated program for calculating the bearing capacity of piles in layered and single-layer soils, thereby improving design efficiency and accuracy. The program integrates various soil models and design standards, taking into account the characteristics of different soil layers and pile conditions. It effectively addresses the base bearing capacity and shaft friction of piles under various soil structures, enabling accurate calculation of the ultimate bearing capacity of piles.

Users can input relevant design data, including soil parameters, pile dimensions, and shapes, through the program’s user interface. Based on static mechanics formulas and frictional analysis models, the program utilizes multiple analysis methods (e.g., API method, Meyerhof method) to calculate the bearing capacity. It generates clear graphical and numerical results, illustrating the trend of bearing capacity variation with depth.

To ensure the accuracy and reliability of the program's calculations, comparisons were made between the program's results, manual calculations, and outputs from the APILE software. The results demonstrate that the program can provide precise bearing capacity calculations within a reasonable margin of error and maintain stability and consistency under different soil and pile conditions.
