%X <p>Accidents such as inclination of pile shaft are common in the construction of prestressed concrete pipe pile.In order to get the bearing capacity behavior of inclined pile-cap system,firstly,we carried out in-situ tests and obtained rational parameters for strata and pile shaft.Then,we computed the structure system of cap with two piles,one of which is inclined,and discussed the system under 3 working conditions.The results show that: bearing capacity of the system is not much affected on the condition of inclination of one pile,in particular,the effect can be negligible under the working condition 3;then the piles axial force increases with the increase of tilt degree of the pile shaft, only in the case 1,the axial force increases first and then decreases;furthermore,the distribution characteristics of moment is similar in three conditions:the maximum moment is located at the top of pile,but when the tilt direction is different,the pile moments symbol is also different;in the general,the maximum value of bearing capacity for three conditions is case 1,followed by case 2,case 3.</p>
