安宁水电站深厚覆盖层工程特性旁压试验研究

Study on Anning hydropower engineering properties of deep overburden lateral pressure test

针对安宁水电站的特点,对深覆盖层上筑坝的适应性进行了研究,并对深厚覆盖层钻孔内进行原位旁压试验,介绍了具体的试验过程及方法,为设计和计算提供地基承载力和旁模量等指标参数。

According to the features of Anning Hydropower Station, the paper researches the adaptability of the damming at the deep overburden layer, undertakes the in-situ lateral loading test in the drilled holes of the deep overburden layer, and introduces the factual test process and method, so as to provide some index parameter for the foundation loading force and lateral modulus in the design and calculation.
