                                                                                                                                                                                                                                                                                                                                                      根據懸臂吊生產、使用經驗分析,懸臂吊基礎事故的原因有以下三類:

                                                                                                                                                                                                                                                                                                                                                      一者部分工地為了搶工期,在混凝土強度不夠的情況下而草率安裝,令到塔吊承重超過地面應力限度,從而發生塌陷、傾翻的不幸事件;

                                                                                                                                                                                                                                                                                                                                                      二者在某些施工單位在塔吊基礎附近進行開挖工作導致滑坡甚至產生位移引發塔吊事故;

                                                                                                                                                                                                                                                                                                                                                      三者由于近年來中國許多城市因地下水抽取過多,產生地下水漏斗,進而引發不均勻的沉降,影響到懸臂吊的運營
