为了克服ABAQUS在进行降雨入渗模拟方面的局限性，采用Python语言对ABAQUS软件的降雨入渗边界进行二次开发，将降雨边界作为不定边界，采用迭代算法对降雨入渗边界进行处理，开发出基于ABAQUS软件的降雨入渗模块。该模块克服了ABAQUS软件中只能模拟降雨全部入渗，入渗率保持不变的单一情况，完善了ABAQUS软件的降雨入渗分析功能。通过与土柱入渗试验进行比较，证明开发出的降雨入渗模块是稳定可靠的。在此基础上，采用该模块研究了抗滑桩边坡的降雨入渗过程，结果表明：抗滑桩虽然可以有效的提高边坡的稳定性，但是，在降雨条件下，抗滑桩的存在减小了排水有效断面，使坡体后缘汇集而来的地下水得不到及时排泄，这又会对边坡稳定性产生不利影响。因此在多雨地区进行抗滑桩设计应充分考虑降雨所带来的不利影响，综合评价抗滑桩的加固效果。借助于ABAQUS的强大功能，该模块可以为以后进行更复杂的降雨相关问题的研究提供一个良好的研究平台。

In order to overcome the limitation of ABAQUS in simulating rainfall infiltration, Python language is used to modify the rainfall infiltration boundary in ABAQUS, the rainfall boundary is considered as an uncertain boundary and is solved by iterative algorithm, and then a rainfall module is developed. This module overcomes the unchanged infiltration rate which is adopted in ABAQUS, thus the ABAQUS’s function in rainfall infiltration analysis is improved. Compared with the column infiltration tests, the validity of this module is confirmed. On this basis, the rainfall infiltration process of anti-slide pile slope is studied. The results show that the anti-slide pile can improve slope stability, however, under rainfall conditions, the anti-slide pile will reduce the effective drainage section, the underground water from trailing of the slope cannot discharge in time, and this will have adverse effect on the slope stability. So, for pluvial regions, the adverse effect of rainfall should be considered in anti-slid pile design. With the aid of the powerful features of ABAQUS, the proposed module may provide a good research platform for more complicated rainfall problems in the future.
