从观2孔地下水30年全程追综看石门拱坝右肩岩体渗透性态

RESEARCH ON THE RIGHT ABUTMENT LEAKAGE CHARACTERISTICS OF SHIMEN ARCH DAM BY TRACING THE UNDERGROUND WATER LEVEL CHANGE OF MONITORING HOLE 2# IN THE WHOLE PROCESS OF 30 YEARS

根据对坝肩观测孔地下水位长期变化的全程追综，研究了一个实际发生在拱坝坝肩上的特殊渗漏问题，即隧洞对石门拱坝右坝肩渗透性能的恶化有重大影响、从该坝曾经发生过的岩体渗透破坏，笔者提出了对拱坝设计的某些想法和意见。

on the traces of underground water level change of an abutment monitoring hole in the whole processs, a special abutment leakage of an arch dam is discussed. The tunnel in the bank deteriorated the leakage characteristics of the right abutment of Shimen arch dam seriously. In views of the leakage rupture happened some ideas are proposed to improve the arch dam design.
