| 5. | For landside correction in excavation project , this paper is based on the stress remolding method and commences to analyze the slope in excavation project : apply loads to the slope and reset the slope in an original stress and make it work like before excavation
对于开挖边坡的滑坡问题，本论文根据应力重塑的方法对开挖边坡进行处理，在坡面上施加荷载，使得边坡土体恢复到未开挖的稳定应力状态；并且利用大型有限元软件ansys来进行等效应力分析。 |
| 6. | According to the special stratum condition 、 soil parameter 、 pile frame system in the protecting landslide of hongtian jianfeng in yongan city in fujian province , compile a fem program of plane strain and analyze the interaction by nonlinear fem on intensity discount . in the program , duncan - chang model is applied to earth , elasticity model is applied to pile and rock ; goodman element is set between pile and rock - earth and applied to simulate sliding plane and flexible floor ; sequential pole elements with original stress are applied to anchor cable
在程序中土体采用了duncan - chang双曲线本构模型，桩和锚固层以下的岩体采用了线弹性本构模型，并且在桩和岩土体间设置了无厚度的古德曼（ goodman ）单元，对于软弱夹层和已知的滑裂面也采用古德曼单元模拟，锚索采用的是具有初始应力的连续杆单元模拟。 |
| 7. | At the same time , the mechanics mode of newly - built structure is not the same as that single cavern is excavated in the half - unbounded space . its original stress field is disturbed by former time and time again , and once more by excavating of later . so the mechanics mode of the later is not symmetrical generally and infinite variability is put up
同时新建结构物的受力模式也不同于半无限体或无限体中修建单一洞室的一般状况，其初始应力场往往是经过多次扰动的，其施工将再次进行扰动，使其受力往往是非对称的，表现出极大的变异性。 |
| 8. | By comparing the original stress , the stress after excavation and the reset stress , we may conclude how to remold the stress in the slope in excavation project . cooperating with expansive anchors , the stress remolding method can increase the anti - slide capacity of slope soils
对原状土体、开挖后的土体以及进行应力重塑后的土体内部的应力进行比较，得出开挖过程的应力损失并进行相应大小的应力补偿以达到应力重塑的目的，使边坡中的土体相当于在自重应力作用下进行工作。 |
