永久船闸开挖基本成形后 ,由于地质结构特点及地应力释放 ,经地质编录确定了 1 0 0m3以上不稳定块体 31 2个 ,直接影响到船闸直立墙的稳定 ,为满足直立墙的稳定要求 ,根据现场情况采取了随机锚索、锚杆等随机支护措施。随机支护的工程量多、面广、时间紧迫 ,经精心组织及时支护满足了直立墙的稳定要求
After the basic shape of the permanent shiplock is excavated, due to the geological structural features and the release of in-situ stress, 31 2 unstable blocks with a size of more than 100m3 have been determined by geological cataloging, which has a direct impact on the stability of the upright wall of the shiplock. In order to meet the stability requirements of the upright wall, , According to the scene to take a random anchor, bolt and other random support measures. Random support of the engineering quantity, a wide range, time constraints, meticulous organization and timely support to meet the stability requirements of erected walls
