    LABORATORY TEST STUDY OF ANCHORING DEPTH FOR ANTISLIDE PILES WHOSE HEAD REINFORCED WITH ANCHOR BAR IN SOIL

    • This paper deals with a special antislid pile whose head is further reinforced and stabilized with bars abchored in soil. Due to the existence of anchor bars,the internal forces and the pile anchoring depth can be greatly reduced. However,the method of calculation is not yet perfect and need a certain amount of engineering experience. The experimental study is very necessary. This paper presents the model test results of earth force in the side of antislide pile of anchor bars. There are three groups of the tests. The loads are on the back side of the slope in two groups. The other one has itsload just behind the pile by jack. In order to get the force of the soil,some earthpressure boxes are put to get the earth pressure on side of the piles. The part of the maximum pressure of the earth pressure is mainly focused under the slip line before the pile and is found by the test. The earth pressure before the pile is got by the test. According with the result of the test,the anchoring depth of the triangle and echelon shapes of the anti pressure is computed and compared the result with what got from the test.
