土木工程类专业课学分占比大，专业课程的课程思政融入路径直接关系到课程思政教学体系建立的成败。将思政元素有机融入专业课堂教学，实现润物无声的育人效果，是土木工程教师的新挑战。以《混凝土结构设计原理》课程为例，探讨了土木工程类专业课课程思政教学目标，支撑点与融入路径。土木工程专业课可围绕政治认同与国家意识、品德修养与专业伦理、学术志向与科学精神等三个维度设定课程思政目标。其中，课程的绪论部分多涉及到课程概述、工程应用、发展历程以及学习方法等。此部分可以挖掘并融入政治认同与国家意识、品德修养与专业伦理两个维度的思政元素。专业知识点章节部分可以通过收集各个知识点的历史文献与经典实验，挖掘并融入学术志向与科学精神维度的思政元素。

The fusion approach of ideological and political education into specialty courses which has a high ratio of the credits determines the success in building up the ideological and political education system. Meanwhile, it is a challenge for the civil engineering teachers of fusing the ideological and political elements into specialty courses seamlessly, and educating students naturally. Design principle of concrete structures was adopted as an example to discuss the aims, strong points and fusion approach of the ideological and political education in specialty courses. In the specialty courses of the civil engineering major, the aims of the ideological and political education can be set in the views of political and national identities, moral characters and professional ethics, as well as academic ambition and scientific spirit. The introduction part of each curriculum always includes the outlines, engineering applications, development history and learning methods of this curriculum. The elements of political and national identities, moral characters and professional ethics can be refined and fused into the introduction part. In the sections of professional knowledges, the academic ambition and scientific spirit elements can be refined and fused into this parts by using the historical literatures and classical experiments in the development of the professional knowledges.
