大中型水利工程灌浆试验的重要性和必要性研究

The significance and essentiality of grouting testing for large and medium-scale water conservancy projects

摘要

灌浆试验是在初步设计或招投标设计之前进行的试验，对前期勘探工程量不足的补充，也可提高其工程的勘察精度，其取得的各种参数可以直接进入工程造价单价分析，指导灌浆设计的完成，在施工灌浆过程中不会导致灌浆工程量的增加而发生设计变更，由而引起工程投资的增大和工期的延长。生产性灌浆试验是在施工灌浆前进行的试验，是验证灌浆设计推荐参数的合理性，但不合理的灌浆参数可能导致重大设计变更而引发工程投资增加和工期延长。因此灌浆试验对于水利工程而言尤为重要和必要。

Abstract

Grouting test is a test carried out before preliminary design or bidding design, which supplements the insufficient amount of exploration works in the early stage and can also improve the investigation accuracy of the project. Various parameters obtained can directly enter the analysis of the project cost and unit price to guide the completion of grouting design, and will not lead to the increase of grouting works and design changes during the construction process. Therefore, the increase of project investment and the extension of construction period are caused. The productive grouting test is the test conducted before the construction of grouting, which is to verify the rationality of the recommended parameters of grouting design. However, the unreasonable parameters of grouting may lead to major design changes, resulting in the increase of project investment and the extension of project duration. Therefore, grouting test is particularly important and necessary for water conservancy projects, especially large and medium-sized water conservancy projects.
