Recycled Aggregate Concrete;Content Of Brick Dregs;Additional Water Content
摘要：
After analysis for the defects and limitations of the existing calculation have been put forward. Regarding the unawareness about a percentage of brick dregs in the recycled aggregate, it designed a test about the water absorption of recycled aggregate with brick dregs and studied the features of water absorption of recycled aggregate with different proportions' brick dregs. Based on the existing calculation methods, it put forward a calculation method of the additional water in the mixing proportion design about the recycled aggregate with brick dregs allocating recycled concrete. It has certain value of application and promotion.
摘要：
With the development of science and technology and continuous improvement of construction technology, the continuous construction technology of long span in bridge construction has been widely used, which has improved the reliability and safety of the bridge. The main features of construction technology includes the basic construction and structural construction of the upper and lower parts of the bridge. In the process of bridge construction, large-span continuous construction technology is mainly used in the construction of cable-stayed bridges, arch bridges and suspension bridges, and has achieved good results. The key to long-span continuous construction technology is linear control, stress control and stability control.

摘要：
With the underground water level falling, the reliable estimates of the stability and deformation characteristics of soil caves in karst region area are required for analysis used for engineering design. Aimed at this goal, combined with practical engineering and field geotechnical test, detail analysis on vertical maximum displacement of top, vertical maximum displacement of surface, maximum principal stress and maximum shear stress were conducted by finite element software, with an emphasis on two varying factors: the size and the depth of soil cave. The calculations on the soil cave show that, its stability of soil cave is affected by both the size and depth, and only when extending a certain limit, the collapse occurred along with the falling of underground water; Additionally, its maximum shear stress is in arch toes, and its deformation curve trend of maximum displacement is similar to the maximum shear stress, which further verified that the collapse of soil cave was mainly due to shear-failure.

摘要：
Heliostat is an important part of the tower solar thermal power generation system. In order to ensure the safety of the heliostat glass panel under wind load, wind resistant design parameters of the heliostat glass panel must be accurately achieved. Through accurate simulation of wind characteristics with the full measurement, heliostat scale rigid model of multi-channel synchronous wind tunnel experiment was conducted and obtained the wind pressure of heliostat panel under various conditions. Based on the analysis results, the gust coefficient for china's specification to design this type of heliostat panel was obtained. The results also show that the actual wind characteristic parameters have a great influence on the value of gust coefficient, and the value of gust coefficient decreases with the increase of the heliostat's height.

摘要：
A single-POF model of disc cutter with rock and soil has been established according to the dynamical feature and vibration mechanism of disc cutter vibro-cutting rock to solve problem of self-adaption vibro-cutting rock for disc cutter, and identification on rock and soil parameter of disc cutter vibro-cutting rock has been carried out by using fuzzy radial basis function neural network. The experimental result of identification simulation and resonant-column test showed that compared to inherent frequency of a hard sandy which was tested by resonant-column test method, the relevant error of rock and soil parameter identification value of disc cutter vibro-cutting rock is 0.87 %, with high estimation accuracy.
摘要：
As a kind of common bridge structure in our country, arch bridge is common in Southwest China, but it is also an area prone to earthquakes in the southwestern area. Therefore, the seismic performance of arch bridge is very demanding. Therefore, based on the simple understanding of the structure and construction characteristics of the steel-concrete composite arch bridge, this paper analyzes the seismic performance of the arch-steel-concrete composite arch bridge in terms of the vibration characteristics, seismic response characteristics, ductile seismic capacity of arch bridge, and seismic performance to provide reference for data information.

摘要：
The contribution of the prestress force on the shear capacity is existed, which is explicit on the vertical component of the prestressed reinforcement in the domestic and foreign standards, but the research on the contribution of horizontal component of prestressed reinforcement is little. Based on the analysis of prestressed concrete T beams, the proposed formula for the shear action of horizontal component of prestressed reinforcement is put forward.
