A review of the extended finite element for fracture analysis of structures Liang Wu1,a, Lixiang Zhang2,b and Yakun Guo3,c 1 Department of Hydropower Engineering, Kunming University of Science and Technology, Kunming 650500, China. 2 Department of Engineering Mechanics, Kunming University of Science and Technology, Kunming 650500, China. 3 School of Engineering, University of Aberdeen, Aberdeen AB24 3UE, U.K.
Since the introduction of the enriched discontinuous solutions into the finite element basic functions helps to avoid tedious remeshing requirement involved with the crack propagation or complicated crack geometries, the X-FEM has now been widely adopted by civil, mechanical, material and aerospace engineering disciplines all over the world and is used to accurately determine the level of performance and safety of cracked structures.

Countermeasures on Environmental Pollution from Construction Changyou ZHANG1,a 1School of Civil Engineering and Architecture, Chongqing University of Science &Technology, Chongqing, P.R.
The right policy should be carried out in environmental protection and main body engineer.
The technical leader or general engineer of project department is responsible for the implement of technical management.
Environmental protection measures must be taken and special programs must be prepared for projects of a certain degree of danger in preparation of design of the construction enterprises Read those drawings before the preparation so as to understand the purpose of design; make the on-site inspection of the geological feature and neighborhood; while the preparation is in process, make it full, operational and instructive according to the characteristics and location of project; after its preparation is done, the program shall be approved by the technical leader from construction enterprises and chief supervising engineer from supervising agency before being put in use. 4.
