Cementitious capillary crystalline waterproofing coating was developed, whose doping quantity of active substances primarily determined by using orthogonal tests, the and cement-sand ratio were optimized, formulation was: 50.45% silicate cement, 40% quartz sand, 2.4% assistants 7.15% chemical substances. Test results showed that all properties developed conform to standard requirements, bonding strength wet substrate reached 1.8 MPa, 28d seepage resistance 1.3 MPa.
The high molybdenum metallization formula is adopted to complete the 95% alumina ceramic metallization. sealing intension, tightness and microstructure are analyzed. experimental results show that: intension of metal due above more than 110 MPa.
To reveal the influence of cracks on dynamic characteristics a two-stage planetary gear transmission system (TSPGTS), nonlinear model with 30-DOF in bending and torsion was constructed, taking into account parameters different crack degrees (depth, angle, length), as well factors such error, time-varying meshing stiffness (TVMS), damping. In model, TVMS components established using potential energy method. By incorporating factor time domain, frequency phase diagram, Poincare diagram...
The treatment of soft soil foundation under nuclear safety grade corridors with graded sand and gravel materials has a good development prospect. It is great engineering value to explore the influence construction parameters on seismic response gallery structures. Taking underground corridor power plant as background, equivalent linear method used consider nonlinear dynamic characteristics gravel. energy transfer boundary applied at truncation simulate dissipation effect scattered wave...
Through analysis of seismic collapse damages buildings during Wenchuan and Yushu earthquakes, structural system method is proposed to expound the relationship between energy analyze their applications in study collapse.
An analytical approach based on branch mode method is formulated in this paper to study the dynamic response of eccentric structure considering soil-structure interaction The superstructure and foundation soil are coupled through aggregation procedure. computational scale system equations decreases an acceptable level. Sample analysis indicate that seismic increases first then with decreasing stiffness soil-foundation system, which affected by inertia effect branch. For soft case, influence...
The bolt connection is one of the main ways railway vehicles connection.The reliability its determines dynamic performance, safety and vehicles.Checking methods coupling strength: mechanical design calculation, finite element "VDI2230" calculation are recognized at home abroad.But present, it less to systematically analyze basic flow, modeling, advantages disadvantages these three methods, especially check bolts same time in ways.This article detailed introduces principle characteristics...
Abstract The stiffness coefficient of steel support plays an important role in controlling the deformation foundation pit, but influence various parameters on supporting effect pit is still unclear, resulting unreasonable value coefficient. By means theoretical analysis and numerical simulation, this paper makes a comprehensive in-depth study law optimization effect. Based calculation support, formula under uniform radial load derived by using basic definition calculation; change rules...
To study the pile‐forming mechanism and bearing deformation characteristics of continuous flight auger (CFA) piles, a series procedures, including helical drilling, pulling up/grouting, inserting cage/pile forming, were simulated in clay‐sand double‐layer foundations by homemade model drilling machine system laboratory tests. The effects two different methods on load transfer piles investigated performing test comparison CFA bored piles. experimental results show that there exist soil...
