摘要
土建工程的安全质量控制的本质，就是运用数理统计原理，归纳、分析实测得到的有关数据，从而达到对现场安全作出准确诊断、对施工质量作出正确评价之目的，其中最常涉及的数学理论知识点是最小二乘原理。本文通过一隧道工程实例，阐明了最小二乘原理在其安全质量预测预报中的作用及使用，颇具实用性操作性地实现了数学理论与工程实际的密切结合。
In the substantially, the security quality domination is the application of concluding, analyzing data with math statistical principle. And then reader could implement aims of making suitable estimation for this data and evaluation of construction quality on locale. The principle, which has highest frequency to be used, is least-square principle. This article elucidates the function of least-square principle and how to use it by an actual example of tunnel project. These methods are useful, exercisable embodiment of close integration between mathematical principles and construction.
