| 摘 要： | 在既有研究的基础上，初步探讨了温度、水、力等因素对红层泥岩崩解的影响机制。研究表明：（1）红层泥岩赋存环境变化引起的要素差，如应力差、浓度差、温度差、水头差、气压差等，是引起红层泥岩裂隙产生的驱动力；（2）水、热、力等因素通过应力重分布、溶解、膨胀、蒸发、毛细、渗流、侵蚀等作用，使红层泥岩的微细观结构产生了不可逆的破坏；（3）水热交替循环的周期效应使微细破坏逐渐累积，直至产生显著的结构破坏；（4）红层泥岩微细裂隙破裂机制是环境要素产生要素差，激发各种物理化学作用，产生各种应力，达到或超过岩石强度，进而引起岩石微细裂隙产生，经过周期累积直至最后脱离坡体剥落的过程。

| Abstract: | Based on the study that has been done, the slaking mechanism of red beds interaction with temperature, water and stress, was studied. Some results were obtained as following: (1) the engines of mudstone slaking are the difference value of stress, concentration, temperature, water pressure, atmospheric pressure, which were evoked by the change of the situation of red beds depositing; (2) the irreversible breaking of red beds' structures were induced by some physical chemistry processes related to water, temperature and stress, such as stress redistribution, solution, swelling, evaporation, capillary, seepage, erosion, et al.; (3) the structure breaking of mudstone was accumulated though the cycling between water and temperature and the seasonal cycling, until the structure destroy happened; (4) It is the difference value of factors that evoke various physical chemistry processes; then some stresses above and beyond the strength of mudstone were set up; the structure breaking are produced, until the rock fragment break away the rock mass though the cycling between water and temperature and the seasonal cycling. |
