Strata and surface movement induced by mining under open-pit final slope is a huge threat to mine safety. Physical model test is an important method to study mining-induced strata and surface movement laws. Because of rock joints predominantly control rock mass deformation and failure, thus physical model test leaving out of consideration of rock joints is difficult to reflect the influence of rock joints on rock mass deformation. Therefore, this paper presents a three-dimensional physical model test considering simplified dominant rock joints. This test process includes the design of testing equipment, the construction of physical model with dominant rock joint sets, conduction of mining and deformation monitoring. And mining under eastern final slope of Yanqianshan iron mine was selected as a case to study the behavior of mining-induced strata and surface movement.

For improving water scenery of Quanzhou city to form a good-looking artificial lake, a barrier is planned to be built in the Jinjiang estuary to store up water from runoff and tide. Some water problems dealing with the barrier construction in the lower reach of the Jingjiang River, such as city flood control and draining waterlogging, water quality, ship passing, and so on, also are concerned by many aspects of whole society. Detail research on these problems for providing a basis of design and operation of the barrier was performed in Nanjing Hydraulic Research Institute according to a physical model test. The result shows that there is a small impact to flood running, and disadvantageous impact to water quality can be reduced to minimal extent by reasonable operation manner of the barrier.
