摘要
取消现有公式中与实际不符的假定,考虑土体实际应力条件,重新推导了临界荷载公式,给出对任意侧压力系数均适用的临界荷载计算公式,并将超固结比OCR引入临界荷载的计算中。在粘聚力、内摩擦角、基础埋深、基础宽度、土体重度、超固结比等因素变动的情况下,着重分析了侧压力系数对临界荷载的影响规律。
Considering the actual stress condition, the inapplicable assume is discarded, and the new formula of critical loads is derived which is suitable for any lateral pressure coefficient. The OCR value is also inducted in the formula. The influence of lateral pressure coefficient on critical bearing capacity is analyzed with the change of cohesive strength, friction angle and so on.
