In the process of rapid development of urban traffic, Chinese intersections have made great progress in meeting the basic needs of urban road traffic, but the intersection design method under the slow traffic system is imperfect.First of all, by analyzing the problems of walking and non-motor vehicle intersections in domestic cities, and comparing and analyzing the excellent foreign cases, the basic idea of fine intersection design is constructed.Finally, take the slow traffic intersection as an example, from the perspective of the traffic individual analysis, the fine design of the intersection under the slow traffic system.Drawing on the organizational experience of the design of foreign intersections under the slow traffic system, it proposes the fine design strategy of urban intersections in China.

At present, the application of surveying and mapping technology in the construction industry plays an important advantage, the application of new surveying and mapping technology to promote the development of the construction industry, the article mainly analyzes the application and optimization of new surveying and mapping technology in engineering surveying.

Experimental studies of some object or phenomenon testing of industrial products control of mechanisms or processes is inconceivable without measurements of physical quantities that characterize the state of the object. Therefore, the composition of any measuring, testing or control system as the most important components includes primary measuring transducers - sensors. The main function of the sensors is to convert the values of various physical quantities into electrical voltage. Strength time parameter of the electrical signal. In the list of tasks that need to be solved in the development and application of measuring systems, one of the most important is that it is necessary to measure not one, but different physical quantities for example, pressure, vibration, rotation speed, deformations, use different in principle of operation, characteristics and sensor design.

China is rich in coal resources. In most cases, coal resources are obtained through the way of mining. In the process of mining, it is necessary to control the application of mining technology, otherwise it will easily cause damage to the geological structure. With the increasing demand of social resources in recent years, shallow mining has been unable to meet the needs of the society, while deep mining is facing the problem of soft rock layer, which can not guarantee the stability and safety. Based on this, this paper will focus on the coal mine soft rock roadway support technology.

In the rapid development of modern society, public libraries are paying more and more attention to the improvement of their own service levels. The deep integration of culture and tourism is an inevitable trend of cultural development in the new period and has largely satisfied the culture of the people. Demand, the practice and development of cultural and tourism integration have promoted the national public libraries to pay attention to the development of cultural and tourism integration and provide support for the development of cultural and tourism integration. The article mainly analyzes the practice and development of cultural and tourism integration in public libraries.
