Analysis of the Type of Contract Price in Construction Projects

In the construction projects, the contract, which is the most important behavior norm, determines the rights and responsibilities of client and contractor. All engineering activities aim at implementing and carrying out the articles of the contract. However, as the key component of the contract, the type of contract price determines the distribution mode of most of the engineering risk between client and contractor. In this paper, the most popular types of contract price used in the international construction projects are introduced. The advantages and disadvantages of each type and the distribution mode of the engineering risk between client and contractor are analyzed. At the end, some advice are given to the clients that they should choose the proper type of contract price and have innovation according to the characteristics of certain project and the situation of themselves.

Numerical simulation of seepage field of gas extraction drilling of single bedding of mining-coal bed

Aiming at the problem of reasonable decorate of coal gas extraction drilling, combining with the initial and boundary condition of borehole extraction, the solid and gas coupling mathematical model of gas seepage of borehole extraction is deduced based on established control equations of seepage field and deformation field. Taking gas extraction of stone coal slit as an example, according to the characteristics of coal seam in the research, the numerical simulation method is used to obtain the distribution rule of gas pressure, coalbed gas permeability, and coalbed gas seepage velocity as well as seam deformation. The effective radius of gas extraction drilling of single bedding about mining-coal bed is determined, which provides the basis for optimum arrangement of gas extraction drilling of single bedding. The results show that the effective radius of stone coal is about 4 m. If the prolonging drilling drainage time is less than 20%, the drilling quantities would reduce by about 50%.
