Abstract
Traditional anchored-plating walls have been used for tens of years to bear large lateral earth pressure in high embankment, slopes, etc. However, because of its own deficiency, such as complex construction, difficult compaction and larger deformation, the application of anchored-plating wall has been limited. Therefore, by combining features of cantilever retaining wall with anchored plates, a new type of retaining wall, multi-anchored-plating wall, was put forward to overcome these questions. Integrating all cables along the height of wall in one section into one anchorage and applying prestressing force along cables would be main features of the type of retaining wall. In order to discuss the difference between cantilever retaining wall, anchored plating wall and multi-anchored-plating wall, field tests have been conducted to investigate the performance. During construction, the lateral earth pressure behind wall, foundation pressure and cable force had been monitored on site. Test results showed that the distribution of lateral earth pressure would be changed greatly after applying prestressed force. The main feature was the stress concentration around the anchorage. Also, lateral earth pressure of retaining wall except anchorage point lied between the \( K_{0} \) line and \( K_{a} \) line. It is observed that there was a serious stress loss for pre-stressed cables because of soil compaction and cable relaxing. And the final remained cable force was about 35–45% of design load.
