In order to generate the digital terrain model, a novel method of using the principle of reverse engineering was introduced.
Then the reversing engineering tool, such as software of “Imageware” was chosen to construct the three dimension terrain surface from the point-cloud data, Fig 4 shows the three dimension terrain surface generated by the method of reversing engineering.

It is the general idea of "Optimizing Design" that the lowest cost is regarded as the optimal design on the premise of engineering safety and reliability.
According to the corresponding standard, in combination with engineering geological conditions, the constraints of the above-mentioned design variables are as follows.
The standard value of bearing capacity of the composite foundation is 120 for the engineering of soft foundation strengthening, it is also required that the designed settlement of this composite foundation is not more than 30.

Introduction In recent years, due to the development of economy, society, science and technology, many engineering problems caused by the extending of underground cavities frequently appear in areas such as water conservancy, transportation, warehousing .
This article will make some preliminary discussion on the choice of extending section of underground cavities and the stability for surrounding rock, which is based on the existing engineering data and engineering projects.
Architect design organization should selected suitable forms, which should be based on the reality of the engineering.

Numerical Analysis of Thermal Response of UHTCs under Aerodynamic Heating Miaoqun Liu 1,a, Hongqing lv 1,b and Zhenqing Wang 1,c 1College of Aerospace and Civil Engineering, Harbin Engineering University, Harbin 150001, China aliumiaoqun@hrbeu.edu.cn, blvhq251@163.com, cwangzhenqing@hrbeu.edu.cn Keywords: Numerical analysis, Aerodynamic heating, Ultrahigh temperature ceramics(UHTCs), Thermal response.
This paper takes the combination of numerical and engineering computation to predict heating flux [1][2].
Based on this method, the parameters of inviscid fluid of boundary layer edge are obtained by solving Euler equations, and then the surface heating flux of wall is calculated by using engineering method.
The heat flux estimated accurately is a prerequisite for the above work, this paper uses numerical calculation combined with engineering calculation[3,4] to solve the Euler equations for the external inviscid flow field, thus the outer parameters of boundary layer are determined, then the Surface heat flux is calculated by the engineering method.
The contours of pressure, density and temperature at symmetry is shown in Fig.2. and the surface heating flux of wall as shown in Fig.3 is calculated by using engineering method.
