The Research Of The Calculative Width Of The Pile Loaded Laterally

In the near future, along with the increase of construction, the laterally loaded piles have been gained more and more application. The calculative width of the laterally loaded pile has been a very important parameter. To study it is to study the pile-rock interaction. But at present the research on the calculative width has been less abroad and home. The text aims at the laterally loaded pile that telescoped the soft-rock, putting up the research on the field test and the account with the program.The pile loaded laterally are actually loaded in three dimension. With the action of the lateral load, owing to the impress of the friction on both side of the pile, there are more and more rock around the pile participate in the interaction. So, the side width of the pile has the prodigious infection. The text introduces the conception of the radial angle, and uses it to explain the inflection of the side width, and establishes the formula of the radial angle. The main contents are as follows: in the first place, the text uses the date gained from field test to work out the calculative width ; in the next place, uses the result of the matrix suction contrast to the date from field test; lastly, the matrix suction contributions to farther analysis, i.e. change of the depth rock-socket and the side width of the pile, and uses them to obtain the calculative width. In the end, the text obtains the standard value of the calculative width by the probability stat theory.
