Based on these , cscec instituted the project ‘ reinforce and mend of the construction ’ , the project is given to research and science institute design of cscec in guizhou 基于這種情況,中國建筑總公司下發(fā)了《建筑物加固與改造技術》的課題,由貴州中建建筑科研設計院承接,主要對加固構件新舊混凝土的粘結進行研究。
Scientific research and design institute of cscec in guizhou cooperate with prof . peng xiaoqin , and research the bond technology of the new and old concrete . which are researched to four points as follows : 1 . several major methods evaluating the degree of roughness were analyzed , and their advantages and disadvantages were analyzed 貴州中建建筑科研設計院與重慶大學材料學院彭小芹教授合作,主要對新舊混凝土粘結技術進行了研究,主要集中在以下幾個方面: 1 .分析目前常用的幾種評價粗糙度的方法,并對每種方法的優(yōu)缺點進行評述;提出一種簡便易行的測量粗糙度的方法,克服目前常用方法的缺點,并通過多組數(shù)據(jù)和灌砂法進行相關性分析,得出兩者之間的關系。
