Nowadays, with the continuous development of building construction in China towards more beautiful and more floors, ensuring the quality of foundation has become the primary factor. Foundation construction is not only the first step of construction engineering, but also the key step. In order to ensure the quality of foundation construction and avoid building inclination or settlement caused by foundation problems, it is necessary to strictly grasp the quality links and ensure that the construction is completed in accordance with relevant standards. The application of foundation detection technology can ensure that the foundation quality meets the requirements of construction engineering and fundamentally improve the overall quality of construction engineering. Therefore, the application of foundation detection technology in construction engineering is of great significance. In this paper, the author deeply analyzes the key points of foundation detection technology of construction engineering and gives corresponding optimization countermeasures for reference to relevant construction units展开更多
