Pile foundation reinforcing method
The invention relates to the technical field of constructional engineering, and discloses a pile foundation reinforcing method. The method comprises the steps of S1, determining an influence area on apile foundation; S2, calculating a bearing capacity Q of the influence area; S3, determining the vertical bearing capacity Q which needs to be borne by a raft foundation, wherein Q= Q ; S4, assuming that the width of the bottom surface of the raft foundation is b, and calculating the foundation bearing capacity fa of the raft foundation; S5, judging whether theactual foundation bearing capacity of the raft foundation is larger than or equal to fa or not, and if the actual foundation bearing capacity of the raft foundation is larger than or equal to fa, executing the step S6; S6, assuming that the length of the bottom surface of the raft foundation is a, calculating the area A of the bottom surface of the raft foundation, and calculating p according toa formula p= Q < vertical >/A; S7, judging whether p is smaller than fa or not, if the p is smaller than fa, determining the length and width of the bottom surface of the raft foundation, and if the pis not smaller than fa, repeating the steps S4-S7 until p is smaller than fa; and S8, performing raft foundation construction. Through the method disclosed by the invention, the bearing capacity of the pile foundation can be guaranteed, the construction process is simple, and the construction period is short.
本发明涉及建筑工程技术领域，公开了一种桩基加固方法。该方法包括：S1.在桩基上确定出影响区域；S2.计算影响区域的承载力Q影；S3.确定筏板基础需承受的竖向承载力Q竖＝Q影；S4.假设筏板基础底面的宽度为b,计算筏板基础的地基承载力fa；S5.判断筏板基础处实际的地基承载力是否大于或等于fa，若是，则执行步骤S6；S6.假设筏板基础底面的长度为a，计算筏板基础底面的面积A，根据公式p＝Q竖/A计算出p；S7.判断p是否小于fa，若是，则确定筏板基础底面的长度和宽度，若否，则重复步骤S4‑S7，直至p小于fa；S8.对筏板基础施工。该方法能够利用并保证桩基的承载力，且施工工序简单，工期短。
