[提要] 在現(xiàn)行地基基礎(chǔ)規(guī)范的基礎(chǔ)上，進行了超常規(guī)的設(shè)計嘗試。根據(jù)工程地質(zhì)特點，為充分利用不同深度的地基土承載力，在基礎(chǔ)底下合理布置剛性長樁及柔性短樁，使樁分別落在不同的土層上，并滿足復合地基承載力和變形要求，從而使樁身強度得到最大限度的利用，取得了很好的經(jīng)濟效益。通過實際工程設(shè)計表明，在一定地質(zhì)條件下，剛?cè)嵝月?lián)合樁的應用不失為一種節(jié)約投資、行之有效的方法?？筛鶕?jù)工程和地質(zhì)特點，推廣應用到其它樁型上。

The rigid long piles and flexible short piles are reasonable arranged in the foundation. Thus the piles will be located at different soil layer,which meet requirements of compound foundation loading capacity and deformation. This design shows that the mix pile in certain geologic conditions is an effective method to save cost and can be widely used in other kind of piles according to engineering characteristics.
