FU Changjiang
2021, 3(9): 8-15.
Abstract (83) PDF (1)
Abstract:
There is an obvious bending-torsion coupling effect during the cantilever construction of a continuous beam bridge with a small radius curve. A temporary locking structure must be installed at the middle pier support to overcome the adverse effects of the unbalanced state and ensure the safety of the construction process. Due to the lack of a reliable temporary lock design check calculation method, the project often uses the combination of the steel tube concrete temporary support pier and the temporary support at the top of the pier to set the temporary lock. Although the safety reserve is sufficient, the cost is high and the construction is difficult. For the purpose of simplifying the temporary locking structure, through in-depth research on the failure mechanism of temporary locking, a practical method suitable for the temporary locking design check calculation of the small radius curved beam bridge body is proposed. It is discussed in detail and demonstrated in conjunction with the refined finite element model. The research results show that the locking design calculation method proposed in this paper has a certain practicability, and has certain reference value for the temporary locking design of continuous beam bridges with small radius curves.

LIU Bingjun
2021, 3(9): 29-32.
Abstract (28) PDF (1)
Abstract:
The filling height in the center of a section of an expressway is 16 m, the filling slope height in some sections is 18 m, the cross slope of the ground is gentle, the natural slope of the ground is 3°～ 8° , in the shape of steps, and the overall slope is about 7 ° . The groundwater is abundant, and the local bedrock is exposed as limestone, sandstone and mudstone. The rock slope is inclined to the ground slope with an inclination of 14° , The loading of the upper fill leads to the overall deformation of the subgrade and the formation of landslide. In this paper, the stability of filling slope with gentle ground cross slope is calculated and analyzed, and the influencing factors of slope stability and slope deformation characteristics are summarized. If the subgrade is filled on the ground where the bedrock is inclined, even if the filling height is small, it will still lead to the instability of the embankment and the sliding of the upper subgrade to form a landslide. Comprehensive treatment measures such as foundation treatment, gravel blind ditch, series water collecting well and anti slide pile have been adopted for the filling slope, and good results have been achieved.

2021, 3(9): 113-115.
Abstract (12) PDF (1)
Abstract:
The finite element model was used to simulate the process of demolishing the bottom middle column of the Ohio State University by means of direct column removal and impact column removal, and the antiprogressive collapse mechanism of the Ohio State University was analyzed, so as to prove the rationality of the simplified model of multi-storey frame structure. Through the comparison between the direct column removal method and the impact column removal method, the results show that: the equilibrium is finally reached after a period of oscillation by the direct column removal method; the impingement point and the node directly above are damaged greatly when the middle column is removed by impingement. It is concluded that the study of progressive collapse resistance should be further analyzed in combination with specific disasters to avoid underestimating the impact of disasters on structures by direct column removal method.
