在拱坝工程中,经常会因为外部的应力导致坝体丧失稳定性,因此传力洞被应用于大坝建设中,它的应用可以使大坝肩的作用力避开大坝的破碎带以及不连续的界面,从而保证大坝的安全运行。迄今为止,传力洞在大坝破碎带基础中的应用已经十分普遍了,但是相关理论研究文献却鲜有报道,本文首先论述了大坝破碎带的基础深度处理,然后阐述了传力洞各项参数的确定,最后总结了传力洞的施工要求及方法,希望为以后工程中的传力洞问题提供一些理论依据。
In the arch dam project, the stability of the dam body is often caused by external stress. Therefore, the force transfer hole is used in the dam construction. Its application can make the dam shoulder force avoid the dam breakage zone and Discontinuous interface to ensure the safe operation of the dam. Up to now, the application of force transfer holes in the foundation of the dam broken zone has been very common, but few relevant theoretical research reports have been reported. This paper first discusses the basic depth treatment of dam break zones, Finally, the author summarizes the construction requirements and methods of the force-transmission tunnel, and hopes to provide some theoretical basis for the transmission-force tunnel in the future engineering.
