The anchorage,which is embedded into the non-homogeneous stratum in most cases,is divided into a series of sub-anchorage segments.

Directing toward the flow design of cantilever anti-slide piles,the thesis which is based on foundation coefficient method and finite element method mainly analyzes service behavior influences by changing several design parameters,such as cross-section type,cross-section size,range interval,strength of rock mass in anchorage zone,bedded length,and so on.

The writers analyze and determine the span of KH in anchorage zone according to the strength theory of rock mechanics and text results of rock samples.

The shear stress of prestressed anchor cable is unevenly distributed along anchoring section, and there are several different methods in the research on the unevenness, but the curves of the shear stress distribution by these methods are not always the same.

In order to calculate the reliability index and failure probability for the stability of rigid anti-sliding pile,performance function was set for the stability of soil body suffering pressure at the side of anchoring section of anti-sliding pile,and JC method was introduced to calculate the failure mode,obtaining reliability index and failure probability.

Distributing form and correspond data of shear stress τ and normal stress σ on the interface of wall rock and resin anchoring section is educed by ANSYS simulation,and shows that anchoring action occurs mostly at deep anchoring section,where under extrusion swell state.

A new method to test stress of anchorage segments of single borehole multiple anchor cables and its application;

Discussion on singularity in deducing lateral shear stress distribution along anchorage section theoretically based on Mindlin’s solution of displacement;

At present,very little test data is available about the peak shear strength between the grout and the bore wall in the interior bond section of prestressed anchorage cable.
