摘要
本研究建立了基于平差方法的基坑边缘变形量计算模型,利用Python编程语言完成有起算数据的经典间接平差程序和无须已知起算数据的边角秩亏网平差程序,针对不同工程条件,对模型进行相应的调整和优化,并对其进行了实验验证.结果表明,该模型具有较高的计算精度和可靠性,能有效地处理复杂地质条件和施工环境下的变形量计算问题.对保障基坑工程施工安全、防止周边环境破坏具有重要意义.
Abstract
This study established a deformation calculation model based on adjustment methods for the edge of foundation pits. Using the Python programming language,a classical indirect adjustment program with starting data and a corner rank deficiency network ad-justment program without known starting data are completed. The model is adjusted and optimized according to different engineering conditions and experimental verification is carried out. The results show that the model has high computational accuracy and reliabili-ty,and can effectively handle deformation calculation problems under complex geological conditions and construction environments. This is of great significance for ensuring the safety of foundation pit engineering construction and preventing damage to the surrounding environment.
