In order to study the force distribution law in the slopes reinforced by pre-stressed anchor cables and frame beams, optimization safety factor calculation method of slopes after reinforcement, the load applied by anchor cables via frame beams is considered as line load on the slope, and we could obtain theoretical solution of additional stress in the slope by means of elastic theory. With parameter...
Exploiting the potential value of dry crust can produce great technical economic benefitis in important projects, especially in highway engineering, but the characteristic of dry crust's stress dispersion on two-layered subgrade needs further study at present. Based on the experimental road section of Xingtai-Linxi highway in soft soil area, the monitoring data of lamination settlement, which has...
Shafts are channels linking the surface part and underground part of mines or hydropower stations, while the numerical simulation of super-deep shafts under construction is scarcely done. In order to promote the construction technology of shafts, a three dimensional FE analysis with surveillance records verification is carried out to simulate the full process of construction to analyze the stress...
In order to know the variation of the slope stability under external slide thrust, the soil load cell was preferred on the test platform of large-scale physical model to measure the stress in the slope body for the first time. Adopting the method of limit analysis of FEM by step load, the The external slide thrust was enhanced step by step with the method of limit analysis of FEM by step loads, the...
One problem when modelling soil compaction is the estimation of vertical stress distribution at the soil surface, as it is non-uniform and mainly depends on soil properties. However, a uniform vertical stress distribution is used in most FEM compaction models. A new processing approach is proposed to numerically model vertical stress distribution at the soil surface, employing the FEM models of PLAXIS...
