Bolt support has been widely used in various rock engineerings for many years, but the bolting behavior of en-echelon fractures has rarely been studied. In this study, the anchorage effect of conventional rigid bolt and energy-absorbing bolt was investigated by direct shear tests under constant normal stiffness conditions. The bolting performance of the two bolts was quantitatively evaluated based on shear strength and dilation indices.  The test results show that the anchorage effect of bolt is closely related to the bolt material and fracture angle. This is essentially determined by the deformation mechanism of bolt in different shear failure structures. A bolt deformation factor was proposed to predict the breakage displacement of bolt at different fracture angles and a bolt contribution index was defined to comprehensively evaluate the bolting performance.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Engineering Failure Analysis, 137, art. no. 106256; 2022","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier Ltd."}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.engfailanal.2022.106256","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2022 Elsevier Ltd.
