【摘要】 应用断裂力学理论和水化学理论，分析了底板隔水层导高带发展机理，指出了应力溶蚀作用是导高带发展的动力．隔水底板中的构造裂隙因水的溶蚀作用、水的楔劈作用和构造应力作用而得到扩张，由此导致导高带逐渐上升，从而减少了有效隔水带的厚度．更多还原

【Abstract】 Based on the fracture mechanics and the water chemistry, the forming and developing mechanism of water flowing crevice zone in water_resisting floor is discussed. It is considered that the stress_corrosion is the motive force of water flowing crevice zone development. The stractural crevice in water_resisting floor is extended because of the water corrosive action, the mechamical action of water pressure and the stractural stress action, which causes water flowing crevice zone gradually to rise.更多还原
