重力坝深层抗滑稳定的可靠度校准

摘要

The standard doesn't give out the determinate safe index about the deep strata anti-sliding stability of gravity dam. The reliability calibration was done with JC method for the condition of shear zone tending to upstream. And yet the dam height, safety factors, etc. how to influence reliability index were studied and discussed here.%对于重力坝的深层抗滑稳定问题，规范并未给出明确的安全指标，为此采用JC法对剪切带倾向上游的情况进行了可靠度校准，并研究了坝高、安全系数等对可靠指标的影响。
