    [Abstract](2594) [HTML](184) [PDF 204.22 K](666) [Cited by](11)
    Abstract:
    The anti uplift performances of pile are closely related to character of the contact surface. The correct selection of the mechanics parameters of contact surface has an important role in the analysis of the anti uplift theory of pile. According to the point surface contact model of pile soil contact surface and Coulomb's friction deformation principle, the value about the pile soil contact surface friction parameters are presented based on the test analysis of ten groups soil structure (steel, concrete) shear friction and conclude that the results will have important reference value for the correct value of pile soil contact surface mechanics parameters.

    18  Discussion of Cavity Development in the Target Area of Intersection Well Pair
    HU Han-yue
    2014, 41(7):20-23.
    [Abstract](975) [HTML](216) [PDF 0.00 Byte](1379) [Cited by](8)
    Abstract:
    As the applications of drilling mining technology are extended from petroleum and salt well to trona solution and CBM mining industries, the thin or weak ledges can provide only a smaller target area, which makes the target-hitting more and more difficult. Different kinds of ranging technology depend on different size of target cavities so as to realize the connection between the drilling well and target well. In this paper, the analysis is focused on the deviation errors produced by MWD and rotary magnet ranging system, and the appropriate size of the cavity development is proposed.
