通过自制试验模型，对坡地地貌岩体基坑在不同降雨强度和坡度下的抗浮水头进行研究，并与有限元程序计算结果对比分析，验证了前期所推导的抗浮水头计算公式的合理性。通过研究进一步表明极端降雨条件下，基坑下游最低点向坑外溢水时，基坑上游水位并不与最低点持平而是持续增长，若取下游最低点作为抗浮水位值，工程将不能满足抗浮要求，存在安全隐患。

Through self-made test model, this paper studies the anti-floating head of slope landform rock foundation excavation in different rainfall intensity and slope. With the finite element calculation results for comparative analysis, this paper verifies the reasonableness of the calculation formula of anti-floating head derived preliminary. By further study it shows that under conditions of extreme rainfall, when the lowest point of foundation excavation downstream spills outside, the foundation excavation upstream water level and the lowest point is not flat but sustained growth. If downstream lowest point is presumed as anti-floating level value, the project will not meet the requirements of anti-floating as well as potential safety hazard.
