In addition, this paper carry out successfully the support design practice in the preceding excavation of 4km long exploratory tunnel. according to the thesis research results, the following conclusion can be drawn. if the grouting rock can possess sound anti - seepage capability and the liner structure can hold higher hydraulic permeability relatively, and if the adjoining rock can be made as primary load - bearing structure by construction measure, the stability of country rock and the safety of liner structure will be guaranteed
計算結果表明，如果能使錦屏工程引水隧洞灌漿圈圍巖具有較好的防滲性能，將高外水壓力控制在灌漿圈以外，再配合透水性相對較好的支護結構以及排水措施，使灌漿圈圍巖成為主要承載結構，並使襯砌結構和灌漿圈共同承載，是可以保證圍巖的穩定和支護結構安全的。 -
The region belong to high geostress area. in the preceding excavation of 4km long exploratory tunnel, several bigger flows had taken place. the maximal flux approached 4. 91m3 / s and the maximal water pressure is 10. 22mpa
在前期4km長探洞施工過程中，曾發生多次較大涌水，單點最大涌水量達4 . 91m ~ 3 s ，長探洞封堵后最大水壓力達10 . 22mpa ，工程區高外水壓力問題突出。
