《中华人民共和国电力行业标准(DL/T5332-2005):水工混凝土断裂试验规程(英文版)》内来自容简介:This Standard is prepared by requirement of "Notice on Printing theDevelopment and Revision Plan of Professi360百科onal Standards"(Document 739, Genera年火夜l Office of the National Development andReform Commission [2005]).
The fracture 增做toughness of con探步号罪所效验发crete is a vital parameter 苦等达forstabi风课相新抓且lity evaluation of crack propagation, crack resistance andanti-c站父东毫决娘缺自尔究racking designs o向支结乙胜激等优f hydraulic concrete structure. Hence it isnecessary to prepare a standar格形言请房d to specify the test methods forfracture toughness of concrete.
This Standard is prepared based on test data 鸡北盐织吧管答座做选about concretefracture collected in the worl未急受信名d, conducting a lot of parallel tests,referring to the fracture test s括领触室强tandards of other coun如比tries, holdingtechnical workshop and discussions focusing on this field, andconducting calculation an力d theoretical analyses.
This Standa育散rd specifies the requirements of wedge splittingmethod and three-point bending beam method. When both of the testmethods are employed simultaneously 委用易的and result in discrepancies,three-point bending beam method shall prevail.
A挥你政个ppendix D of thi弱规核空益保露各笑善差s Standard is normative; Appendix A, B, Cand E are informative.
This Standard is proposed by China Electricity Council.
This Standard is under the jurisdiction and the explanation of theT担视的院先圆误位空南春echnical Committee of Standardization for Hydropower Construction ofElectric Power Industry.
