Self-saturation pore pressure probe for roadbed sounding and saturation and pressure measurement calibration method
A self-saturation pore pressure probe for roadbed sounding is characterized in that a pressure liquid storage cavity combination is arranged in the pore pressure probe, and saturated liquid with pressure is stored in the pressure liquid storage cavity combination; the pressure liquid storage cavity combination is communicated with the conical head combination, saturated liquid in the pressure liquid storage cavity combination enters a pressure measuring cavity of the conical head combination under the action of pressure and then seeps out through the permeable filtering ring, and therefore it is guaranteed that the permeable filtering ring and a pore pressure system are always in a saturated state in the working process of the pore pressure probe. Therefore, the method has the advantages of high test precision, high response speed and reliable test data. Besides, the sensor structure for the conical head resistance and the side wall friction force of the pore pressure probe adopts the integral force transmission cylinder, and the integral force transmission cylinder is arranged in the friction cylinder, so that the pore pressure probe has excellent integral rigidity and strength, the service life of the pore pressure probe is prolonged, and the stability of a test result is improved.
一种路基触探用自饱和孔压探头，在孔压探头内部设置了压力储液腔组合，压力储液腔组合中存储有带有压力的饱和液；压力储液腔组合与锥头组合连通，压力储液腔组合中的饱和液在压力作用下进入锥头组合的测压腔，再经透水过滤环渗出，因此确保了孔压探头在工作过程中透水过滤环及孔压系统始终处于饱和状态，因此具有测试精度高、响应速度快、测试数据可靠的优点；另外，孔压探头的锥头阻力及侧壁摩擦力的传感器结构采用整体式的传力筒，整体式传力筒设置在摩擦筒中，使孔压探头具有极佳的整体刚性和强度，因此使孔压探头的使用寿命及测试结果稳定性均得到提高。
