The most of shaft wells of TGP s permanent shiplock characterize as large section, shaft well group, double steel bar, and large amount of accurately embedded metal structure and especially for the lower shiplock chamber section, the structure is complicated and the steel bar is dense.

The outfall pressure shaft well in the third-step pumping station of main canal of Wanjiazhai Huanghe Water Transfer Project in Shanxi Province is lined with reinforced concrete and constructed by using hydraulic climbing form.

In order to protect the cast concrete at the shaft well section of the power tunnel against corrosion by several strong corrosive mediums,a protection project at the outer sidewall of the shaft well is needed.

Using the basic design theory of vertical well and summing up with the experiences in several vertical well constructions in tunnel engineering, the paper puts forward a calculation method for the lateral pressure of vertical well in the loess area.

In this article, authors firstly introduce the design and construction of these vertical wells, analyze reasons of their sedimentation from such aspects as dimensions, practical construction situations, and soil features and so on, and finally state several sedimentation treatment measures adopted in construction.

Then the requirement of similar speed field is deduced and the subsectional model experiment is put forward on the basis of the peculiarity of pressure distribution in continuous state vertical well.
