| Calculating method of passive earth pressure in front of diaphragm wall during construction of deep-large foundation pit with central island method |
| 摘要 |
| 針對(duì)中心島法開(kāi)挖基坑問(wèn)題，基于平面滑裂面假定，得到了墻前預(yù)留土體被動(dòng)土壓力的解析解，利用此解可以得出擋土墻和預(yù)留土體保持穩(wěn)定的土壓力判據(jù)。作為該方法的特例，位于直立擋土墻后無(wú)限黏性土坡的被動(dòng)土壓力計(jì)算公式被確定。計(jì)算結(jié)果與有限元結(jié)果對(duì)比表明，當(dāng)土與擋墻背 |
