浅谈秦沈客运专线补充定额的测定

Discussion on determination of additional norms for Qinhuangdao - Shenyang passenger special line

秦沈客运专线在施工中所采用的新技术、新工艺和新材料较多,在设计标准、质量要求和施工工艺等方面都比普通铁路高。如何针对快速客运专线和高速铁路工程的特点,制定出适应此特点的各种定额已成为当务之急。笔者曾参与了秦沈客运专线部分补充定额的现场测定工作,通过对秦沈客运专线路基工程中部分分项工程的施工工艺和工程经济进行的调查分析和研究,以及对补充定额的调查测定工作作了初步探讨,可供正在调查补充定额的同行们参考。

A lot of new techniques, technology and materials are employed in the construction of Qinhuangdao - Shenyang passenger special line. Of the said line, the design standards, quality requirements and construction technology are set higher than conventional railways. It is an imperative task to work out the norms of various kinds to suit the characteristics of fast speed passenger special lines and high speed railway projects. In view of the above, the Ministry of Railways assigned in 1999 the task of preparing additional norms for railway projects with a speed of 200km/h. The author of this paper participated in the field work to determine part of the additional norms for the aforesaid special line. Through the investigation, analysis and study of the construction technology and engineering economy of part of the engineering items in the roadbed project of the special line along with the study of the investigation and determination work of the additional norms, the paper can provide certain reference to colleagues who are making investigations into the additional norms.
