摘　　要：在土力学教学、学习及实际岩土工程设计计算中,土壤三相比例指标的换算是必备的基础技能。同时,土壤三相比例指标计算较为繁琐且易出错,会影响到学生对课程学习的兴趣,不利于学生对知识点的掌握。为提高教学质量,运用C++编程语言开发了一个可用于计算土壤三相指标的实用计算程序。该程序梳理选取8个常用土壤三相比例指标,利用其中任意3个已知指标,通过求解非线性方程组得到3个基本指标,再进一步计算得到其他换算指标。该程序不仅为土力学教学提供一个辅助教学工具,也为学生将来运用土力学知识解决复杂岩土工程问题提供一个简便计算工具。In the teaching and learning process of soil mechanics and the practical design calculations of geotechnical engineering,the conversion of soil three-phase ratio index is an essential fundamental skill.At the same time,the calculation of soil three-phase ratio index is tedious and error-prone,which can affect students'interest and hinder their mastery of the knowledge points.In order to improve the quality of both teaching and learning,a practical program for calculating soil three-phase index is developed with C++programming language.The program selects 8 commonly used soil three-phase ratio indexes,and by utilizing any three known indexes,it solves a system of nonlinear equations to obtain 3 basic indexes,and further calculates other conversion indexes.The program not only provides an auxiliary teaching tool for soil mechanics teaching,but also provides a simple calculation tool for students to apply soil mechanics knowledge to solve complex geotechnical engineering problems in the future.
