The utility model relates to a stress test's technical field, more specifically relates to a pore water stress test system, force transducer and a plurality of water pipe that is used for transmitting pore water stress are answered including the pore water that is used for installing mud messenger its sedimentary sediment column, handover measurement pore water stress element, being used for responding to pore water stress to the test system. Force transducer is answered to handover measurement pore water stress element configuration one high accuracy differential pressure style pore water. Install on sediment column's lateral wall about in proper order, the other end is connected with handover measurement pore water stress element by the interval for a plurality of water pipe one end. The test system also includes the correction post, the correction post also is connected with the handover measurement pore water stress element through the water pipe. Through the setting that the interval was installed on sediment column's lateral wall about in proper order, the other end and handover measurement pore water stress element are connected of a plurality of water pipe one end for the cost just can both have been saved to a plurality of pore water stress test that carry on to the one sensor, and it is very convenient again to use.
