| 1 | The behavior of a rectangular closed diaphragm wall when used as a bridge foundation显示文摘The rectangular closed diaphragm(RCD)wall is a new type of bridge foundation.Compared to barrette foundation,measuring the performance of RCD walls is relatively complicated because of their incorporation of a soil core.Using the FLAC3D software,this paper investigates the deformation properties,soil resistance and skin friction of a laterally loaded RCD wall as well as the settlement,axial force and load-sharing ratio of a vertically loaded RCD wall.Special attention is given to the analysis of factors that influence the performance of the soil core.It was found that under lateral loading,the RCD wall behaves as an end-bearing friction wall during the entire loading process.The relative displacement between the wall body and the soil core primarily occurs below the rotation point,and the horizontal displacement of the soil core is greater than that of the wall body.Under vertical loading,the degree of inner skin friction around the bottom of the soil core and the proportion of the loading supported by the soil core increase with increased cross-section size.The wall depth is directly proportional to the loading supported by the outer skin friction and the tip resistance of the wall body and is inversely proportional to the loading borne by the soil core. | Qiangong CHENG Jiujiang WU Zhang SONG Hua WEN | 2012 | Frontiers of Structural and Civil Engineering2012，6，4： | 13 |
| 2 | Diaphragm wall-soil-cap interaction in rectangular-closed-diaphragm-wall bridge foundations显示文摘Rectangular-closed-diaphragm-wall foundation is a new type of bridge foundation.Diaphragm wallsoil-cap interaction was studied using a model test.It was observed that the distribution of soil resistance under the cap is not homogeneous.The soil resistance in the corner under the cap is larger than that in the border;and that in the center is the smallest.The distribution of soil resistance under the cap will be more uniform,if the sectional area of soil core is enlarged within a certain range.Due to the existence of cap,there is a“weakening effect”in inner shaft resistance of the upper wall segments,and there is“enhancement effect”in the lower wall segments and in toe resistance.The load shearing percentage of soil resistance under the cap is 10%–20%.It is unreasonable to ignore the effects of the cap and the soil resistance under the cap in bearing capacity calculations. | Hua WEN Qiangong CHENG Fanchao MENG Xiaodong CHEN | 2009 | Frontiers of Structural and Civil Engineering2009，3，1： | 5 |

| 4 | Field testing of geosynthetic-reinforced and column-supported earth platforms constructed on soft soil显示文摘这份报纸集中于行为增强 geosynthetic 、支持列(GRCS ) 在软土壤的地球平台。由分析监视工程的 15 月的长域的数据, GRCS 地球平台的适用的行为和有效性详细被讨论。充满什么时候到达某个高度,能被发现拱的土壤被产生。在四堆积的中心对土壤起作用的测量压力比那小对在二堆积之间的土壤起作用。延伸和位于在堆积之间的土壤的 geogrid 的紧张两个都比堆积顶上的相应价值大。堆积的皮肤磨擦在有低力量的土壤层是相对小的,在那些层的轴的力量的负担转移是重要的;同时,相反的状况与高力量发生在土壤层。在浅地点的毛孔水压力与充满的高度稍微增加并且是极大地由增加假装了充满负担。分层的解决与充满的高度直接成正比,并且相应数量与地点和特定的土壤层的性质相关。另外,堤的侧面的排水量与更大的装载增加并且与增加的深度减少。这些建议 GRCS 系统的使用能减少侧面的排水量并且显著地提高一个堤的稳定性。 | Qiangong CHENG Jiujiang WU Dongxue ZHANG Fengping MA | 2014 | Frontiers of Structural and Civil Engineering2014，8，2： | 2 |
| 5 | Performance of rectangular closed diaphragm walls in gently sloping liquefiable deposits subjected to different earthquake ground motions显示文摘The performance of rectangular closed diaphragm walls(RCDW)subjected to earthquake ground motions is extremely complicated in gently sloping liquefiable deposits and requires further investigation.A nonlinear finite element(FE)model was developed to investigate the seismic performance of an RCDW in the OpenSees platform.Initially,the feasibility of the FE model to simulate the seismic behavior of the RCDW was validated by comparing the numerical results with the experimental data.The numerical results agree well with the centrifuge test data.Then,the calibrated model was used to study the seismic performance of the RCDW subjected to different ground motions in gently sloping liquefiable deposits.The numerical results indicate that the soil-RCDW system under near-fault ground motions is more likely to be damaged than that under far-fault ground motions.The difference between the maximum and minimum(Dmax-min)the RCDW displacement and the maximum excess pore pressure in the soil core increased as the Arias intensity increased.The seismic response of the soil-RCDW system was strongly affected by the frequency content,durations,energy distribution and initial directions of the ground motions.Moreover,the modified specific energy density(MSED)has a good linear relationship with the Dmax-min of the RCDW displacement. | Zhang Jianlei Cheng Qiangong Li Yan Qiu Yuheng Wang Yufeng Wu Jiujiang | 2021 | Earthquake Engineering and Engineering Vibration2021，20，4： | 2 |

| 12 | Numerical modeling of current-induced scour around multi-wall foundation using large-eddy simulation显示文摘Scouring is one of the primary triggers of failure for bridges across rivers or seas.However,research concerning the scour mechanism of multi-wall foundations(MWFs)remains scarce,hindering the further application of MWFs.In this study,for the first time,the scouring effect caused by unidirectional flow around MWFs was examined numerically using FLOW-3D involving a large-eddy simulation.Initially,the applicability of the scouring model and input parameters was validated using a case study based on published measured data.Subsequently,the scouring effects of four MWFs with different wall arrangements and inflow angles,including the flow field analysis and scour pit and depth,were investigated thoroughly.It was found that the maximum scour depth of MWFs with an inflow angle of 0°was smaller than that of those with an inflow angle of 45°,regardless of the wall arrangement.Meanwhile,changing the inflow angle significantly affects the scour characteristics of MWFs arranged in parallel.In practical engineering,MWFs arranged in parallel are preferred considering the need for scouring resistance.However,a comparative analysis should be performed to consider comprehensively whether to adopt the form of a round wall arrangement when the inflow angle is not 0°or the inflow direction is changeable. | Jiujiang WU Lingjuan WANG Qiangong CHENG | 2023 | Frontiers of Structural and Civil Engineering2023，17，4： | 0 |
