To analyze the excavation stability and reasonable reinforcement measures of cutting slope with a goaf collapsed roadway mining face, finite element software Midas GTS NX was used to model change in coefficient under different ratios. Combined scope project land, it is proposed that ratio grades 1–3 (close top cut) 1:1.5, while 4–6 bottom 1:1, excavate slope. During process, plastic zone after ...

Mountain Flood Control Reservoir (MFC Reservoir) is used to reduce the flood level in mountainous area and protect settlements downstream. The special feature of this MFC fast filling during 1-2 days, short storage time at maximum speed falling water level. Simulation operation was carried out on software Midas GTS NX. Two rockfill dam models were developed: with core screen. fluctuation taken ...

This paper includes the investigation of soil–structure interaction (SSI) effect on seismic response 20 and 30-story reinforced concrete moment resisting frames (MRFs) rested a piled raft foundation using direct approach. After that, study is conducted to show impact cellular instead designed solid dynamic building. A introduced select best gap size for raft. The soil model assumed as single la...

To investigate the changes in soil dynamic response around tunnel periphery under vibration loads generated by train operation on curved sections, field measurements were carried out to observe void water pressure, level, and settlement ground. Additionally, simulation modeling using MIDAS was employed simulate analyze soil’s impact of loads. Based track stress diagram combined with axle weight...

The setting of the late poured band is an effective measure to control differential settlement and stress concentration foundation. However, lag pouring time will also bring adverse effects construction process. Taking a large commercial complex as example, Midas GTS NX finite element software used for overall foundation modeling, collaborative calculation carried out by adjusting composite sch...

Urban overpasses, being long-span linear projects, are inevitably affected by ground fissure activities. This study focused on the three-span continuous overpass, and used MIDAS GTS NX finite element simulation software to establish model of an urban overpass crossing active fissures with different straddling positions hanging wall settlements. analyzed deformation stress characteristics soil b...

When constructing subway tunnels in coastal cities, boulders with high strength and large volume are often encountered. A number of engineering practices have shown that the existence will destroy unity homogeneity stratum. If tunnel is not properly handled during crossing construction, it lead to collapse surrounding rock; serious cases, may induce ground collapse, damage buildings, endanger s...

The upward shield method in horizontal tunnels has the advantages of small ground space occupation, low construction cost, and short period, which expresses substantial economic benefits. special segments corresponding to area have design requirements, different internal force calculations analyses should be carried out. To determine mechanical behavior segment structure during tunnels, theoret...

The development of reinforcements for soil has made an impact in most the civil engineering sectors especially transportation. use geogrids is frequent roadways but they are also finding railways. major that could have providing desired stiffness to a section by reducing material and serving as proper reinforcement material. In current study, attempt been redesign railway embankment economicall...
