Armor block anti-falling stability testing device and testing method
The invention provides an armor block anti-falling stability testing device. The armor block anti-falling stability testing device comprises a lifting appliance, a dynamometer, a force transmission component, a force application mechanism and a block instability displacement measuring mechanism, wherein the lower end of the lifting appliance is connected with an armor block, and the upper end of the lifting appliance is connected with the lower end of the dynamometer; the upper end of the dynamometer is connected with the lower end of the force transmission component; the upper end of the force transmission component is connected with the force application mechanism; the block instability displacement measuring mechanism is mounted on the upper surface of an unaffected armor structure at the periphery of the armor block; and the force application mechanism applies a pulling force to the force transmission component, so that an extension line is formed from the lower end point of the dynamometer to the upper end point of the dynamometer and the force transmission component at the upper end of the dynamometer, the extension line is consistent with the jumping or lifting instability direction of the upper surface of the armor block, and an eccentric distance exists between the extension line and the gravity center of the armor block. The invention further provides an armor block anti-falling stability testing method. The armor block anti-falling stability testing device is ingenious in structure and suitable for testing the maximum external force borne by a regular or irregular armor block before instability.
一种护面块体抗脱稳定测试装置，包括吊具、测力计、传力部件、施力机构和块体失稳位移测量机构，吊具的下端与护面块体连接，吊具的上端与测力计的下端连接；测力计的上端与传力部件的下端连接；传力部件的上端与施力机构连接；块体失稳位移测量机构安装在不受影响的护面块体周边护面结构的上表面上；施力机构向传力部件施加拉力，使得测力计的下端点向测力计的上端点、测力计上端的传力部件方向形成的延长线，延长线与护面块体的向上表面的跳脱或掀脱失稳方向一致，延长线与护面块体的重心之间存在偏心距。以及提供一种护面块体抗脱稳定测试方法。本发明构造巧妙，适用于测试规则或不规则护面块体失稳前承受的最大外力。
