Test device and test method for simulating piling on reef limestone
The invention provides a test device for simulating piling on reef limestone, the test device comprises an upper support and a lower support which are detachably connected, the lower support is provided with a plurality of mounting positions, a test box for simulating a marine environment is arranged below the upper support, the upper support is provided with a brake for providing power for a test pile, and the brake is connected with the mounting positions. The brake comprises a jack used for providing static pressure power and a vibration exciter used for providing vibration power, the jack and the vibration exciter are arranged in the direction of the multiple installation positions, and when the upper support is installed at the different installation positions, the jack or the vibration exciter and the test box correspondingly conduct static pressure pile sinking or vibration pile sinking tests. The test device is a static pressure and vibration integrated device, the jack corresponds to the test box or the vibration exciter corresponds to the test box by changing the relative position of the upper support and the lower support, and the test device has the static pressure pile sinking and vibration pile sinking test capacity.
本发明提供一种模拟礁灰岩上打桩的试验装置，包括可拆卸连接的上部支架和下部支架，所述下部支架设置有多个安装位，所述上部支架下方设置有用于模拟海洋环境的试验箱，所述上部支架上设置有用于为试验桩提供动力的制动器，所述制动器包括用于提供静压动力的千斤顶和用于提供振动动力的激振器，所述千斤顶和激振器沿多个所述安装位的方向布置，用于上部支架安装在不同安装位时千斤顶或激振器与试验箱对应进行静压沉桩或振动沉桩试验。该试验装置为静压、振动一体装置，通过改变上部支架和下部支架的相对位置，使得千斤顶与试验箱对应或激振器与试验箱对应，使得该试验装置具备静压沉桩和振动沉桩试验的能力。
