Taking one foundation project as an example, a series of tests are carried out to study the dynamic compaction parameters and its effects on the deep collapsible loess foundation under super high fill in Lvliang region. Analyses are made on the average settlement of each test area before and after dynamic compaction and on the regularity of the main physical and mechanical indexes of soil. At the energy levels of 2000 kN•m, 3000kN•m and 6000kN•m, the main parameters are gained, such as the effective reinforcement depth, the centre distance of tamping points , the standard of stopping ramming, and the optimal ramming number; hence, the empirical formula of the effective reinforcement depth of dynamic compaction. The results of the tests show that the deep collapsible loess foundation in Lvliang region can be effectively reinforced by dynamic compaction, that the stability of foundation is good, and that the loess collapse in the reinforced range is eliminated basically. Moreover, after dynamic compaction above the energy levels of 2000 kN•m, the eigenvalue of the bearing capacity of collapsible loess foundation in Lvliang can reach over 300kPa; the deformation modulus of foundation soil is more than 25MPa. Therefore, the results of the tests can provide a reference for the design and construction of projects of the same kind; it can also provide a reliable basis for relevant norms and standards.

This research is to integrate the QFD and TRIZ theories into innovative principles of the intelligent patient bed design processes. The use of the QFD matrix expansion and its importance for the evaluation and analysis to build the front-end preventive design process will meet customer needs. The evaluation is based on the order of importance; the quality characteristics of the target specifications and quality characteristics of the correlation matrix. The design of an integrated sensor system to monitor patients‟ body movements while lying on beds enables the data quantity to be collected and analyzed to identify the cause of bed sores and the spots that bed sores are prone to occur. Armed with this information, designers and engineers can work to develop much-improved and market competitive products, which is the focal point of this article. Doctors can then treat patients more efficiently and effectively. All physical response data derived from the patients (testers) are documented to assess the correlations between the sensors and the human body. During the test time, the mechanism was activated, and all of which were able to effectively facilitate the reduction of bed sores for the patient by the intelligent patient bed.

Based on analysis of five different conditions’ full scale model tests of the fastener tubular steel scaffolding, the paper introduces that notional lateral loads can imitate the effect which generalized imperfections of the falsework(initial imperfections, node semi-rigid and so on) give the bracket’s stability capacity. According to the finite element software ANSYS, the falseworks’ stability capacities of different conditions have been imitated and analysed, Analysis results compare with test results. The final result indicates that it is reasonable that notional lateral loads in certain scope can imitate generalized initial imperfection. Research results can be used for on-site t technical personnels’ design and safety control.

Used of finite element software, based on the material characteristic and node semi-rigid experimentations, the model with material multi-linear kinematic hardening and node semi-rigid was established to simulate the test model of coupler steel tube falsework. According to the measured data of the defect, to analyze the nonlinear stability of the model by methods of the consistent defect mode and stochastic defect, the results indicate that the model’s correctness and consistent mode imperfection method’s in analyzing coupler steel tube falsework is feasible, and the structure is a defect-sensitive structure. The brittleness failure characteristic of coupler steel tube falsework was validated and several effective conclusions were educed after comparative study on the deformation mode and load-displacement curve of the test, consistent defect mode method and stochastic defect method.

This paper proposes how QFDs, TRIZ integration with FMEA may arise, and making the control valve in the design concept and manufacturing development stages to amend the main issues to have front-end prevention. In order to eliminate the conflicting requirements and to build the front-end prevention of the design and production process that will meet customer needs and translate customer requirements into measurable technical requirements, the innovative model integrating three tools is proposed. One case is given to illustrate the research steps for the proposed model that will demonstrate the design quality and achievable resource benefits when these three tools provide product developers with more useful information and precise analysis results.
