Abstract
The longitudinal cofferdam of Xiangjiaba Hydropower Station was built on deep overburden layer , therefore the se-lection of reasonable foundation treatment scheme was the key for the smooth construction diversion .After repeated comparison -selection and research , the large sinking well group composed of 10 sinking wells was determined .Through innovating the design concept of sinking well group , the thought of large sinking well with small interval was put forward and in the combination of the practical condition , the plane arrangement , structural design , underground seepage control were suggested .Aiming at the com-plicated conditions of small well interval , large sinking depth , thicker overburden layer , large difference of stratums containing big boulder , the optimized sinking construction measures were proposed .The rock filled concrete was applied to fill the sinking well, thus satisfactory technological and economical effects were obtained .关键词
