摘要

Abstract xml:lang="de">Sp?testens seit Referenzierung in den Allgemeinen Technischen Vertragsbedingungen der VOB/C ist der Cerchar‐Abrasivit?tsversuch in Deutschland als Standardverfahren zur Beschreibung der Abrasivit?t von Festgesteinen anzusehen. Der Versuch wird üblicherweise auf Basis der in 2016 ver?ffentlichten Empfehlung Nr. 23 des Arbeitskreises 3.3 ?Versuchstechnik Fels“ der DGGT ausgeführt. Um die praktische Anwendbarkeit und den Wert dieser Empfehlung für eine einheitliche Versuchsdurchführung zu überprüfen, wurde im Rahmen einer Masterarbeit an der TU Darmstadt ein Cerchar‐Ringversuch mit 17 felsmechanischen Laboren aus Deutschland und ?sterreich organisiert und als Pr?zisionsversuch nach DIN ISO 5725 ausgewertet. Es zeigt sich, dass der Cerchar‐Versuch nach DGGT‐Empfehlung Nr. 23 als grunds?tzlich geeignetes Mittel zur Einsch?tzung der Abrasivit?t von Festgestein betrachtet werden kann. Bei der Interpretation der Ergebnisse sollte jedoch stets die Streuung der Messwerte berücksichtigt werden, die in erheblichem Ma?e von der Zusammensetzung und dem Gefüge des geprüften Gesteins abh?ngig ist. Diese Streuung l?sst sich mithilfe der Ergebnisse des Cerchar‐Ringversuchs erstmals quantitativ absch?tzen. Darüber hinaus k?nnen Empfehlungen zur weiteren Optimierung des Versuchsablaufs abgeleitet werden. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><abstract type =“main”xml：lang =“de”> <标题类型=“main”>抽象</ title> XML：LONG =“DE”>后来从VOB / C一般技术合同条件中引用，德国陶瓷磨蚀试验应被视为描述固体岩石磨料的标准程序。该实验通常是根据工作组的第23号建议（3.3？实验技术岩石“的建议书来进行。为了检查本建议书的实用适用性和价值，德国17辆岩石机械实验室的陶瓷环尝试和？奥地利被组织为TU达姆施塔特硕士学位的一部分，并评估为受欢迎的尝试到DIN ISO 5725。事实证明，根据DGGT建议书的陶瓷实验，可以被认为是耗尽固体岩石磨料的合适装置的原理。然而，在结果的解释中，应始终考虑测量值的散射，这取决于对构件的相当大测量和测试岩石的结构。该散射可以通过CERCHAR环实验的结果定量地适合。此外，可以获得建议以进一步优化实验程序。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-23495/'>《Geotechnik: Zeitschrift fuer Bodenmechanik, Erd- und Grundbau, Felsmechanik, Ingenieurgeologie, Geokunststoffe, Deponien, und Altlasten》</a> <b style="margin: 0 2px;">|</b><span>2019年第3期</span><b style="margin: 0 2px;">|</b><span>共9页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lange Tristan&option=202" target="_blank" rel="nofollow">Lange Tristan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Plinninger Ralf J.&option=202" target="_blank" rel="nofollow">Plinninger Ralf J.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Henk Andreas&option=202" target="_blank" rel="nofollow">Henk Andreas;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>PG – Dr. Plinninger GeotechnikKirchweg 16 94505 Bernried;</p> <p>PG – Dr. Plinninger GeotechnikKirchweg 16 94505 Bernried;</p> <p>Lehrstuhl für IngenieurgeologieTechnische Universit?t DarmstadtSchnittspahnstra?e 9 64287 Darmstadt;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/165.html" title="地质学">地质学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Abrasivit?t&option=203" rel="nofollow">Abrasivit?t;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Cerchar‐Abrasivit?ts‐Index (CAI)&option=203" rel="nofollow">Cerchar‐Abrasivit?ts‐Index (CAI);</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=DGGT‐Empfehlung Nr. 23&option=203" rel="nofollow">DGGT‐Empfehlung Nr. 23;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ringversuch&option=203" rel="nofollow">Ringversuch;</a> </p> <div class="translation"> 机译：磨石？T;CERCHAR-磨料？TS-INDEX（CAI）;DGGGT建议书 23;戒指尝试;
