Ecological Engineering methods are engineering methods that follow the laws of nature and accord with the natural environment.
Engineering classification and tectonic units of ecological engineering methods Water Bank with good natural vegetation is a natural and solid revetment.
The following are the instructions to tectonic units and engineering classification.( Fig.1) Fig 1 Engineering classification and tectonic units of ecological engineering Engineering method.
Engineering method is an approach in which the engineering needs is met only by the use of civil engineering structures which includes traditional flood control project and water management project But considering the ecology, materials and construction techniques conforming to ecological requirements should be selected (such as a porous structure designed to create environment conducive to the natural growth of plants and in line with lives of the local aquatic or amphibious creatures)and try to avoid the use of concrete and other man-made materials in order to make engineering structures meet the needs of ecology and landscape in its appearance and function.
The hybrid method of vegetation and engineering.

Introduction Most of current work on safety of civil engineering structures deals with evaluation of structural reliability, and there is not much study on the assessment and detection of structural damage.
Nowadays, as more civil engineering structures reach to or close to their lifetime and a great number of large-scaled civil engineering structures are being built worldwide, damage assessment and detection technology of civil engineering structure has been of great importance and needs to be urgently developed.
For a large amount of concrete structures in civil engineering, the most direct manifests of damage occurrence are the appearance and broadening of cracks [2].

Artificial neural networks can be used for building prognostic models of various engineering problems.
But, the fast engineering development and the dominance of high structures imposed the requirement of structure’s stability and safety during a fire.
The application of neural networks for building a prognostic model which will be used for estimation of the time of fire resistance for structures and/or their elements is of huge importance for the design process in civil engineering.
This positive effect completely justifies their application as prognostic models for solving any complex engineering problem.

Total Cost Management of the Engineering in Design Phase Ying Cao1, a, Ping Zhang 2,b 1 School of Civil Engineering, Henan University of Science and Technology, Henan, China 2 School of Civil Engineering, Henan University of Science and Technology, Henan, China acaoying1209@163.com, bpjmsy@163.com Keywords：total cost management (TCM), design phase, project cost Abstract：Design phase is the important phase of cost control which is one of the pivotal factors for perfectly realization of the project，and it owns the characteristics of substantive investment，far-ranging social benefit，long time limited for a project etc．Some advices and measures to cost control in design phase were put forward according to TCM(Total Cost Management)and the better effect．
The engineering design is important for the controlling of the basic construction investment scale, constraints on the project cost and increasing investment returns.
The practice shows the influence that the design phase exerting on total engineering investment is about 75%-95%, but the impact resulting from the construction stage is only 5%-25%.
Lack of risk awareness in the design phase.According to one of the foreign statistics, design factors took up 40.1% among all the causes of the accident in civil engineering, ranked first(Given in Table 1).In China, on the statistical analysis of the causes of 514 projects in construction industry , engineering design also accounted for 40% among all the factors.
The construction of project is a complex system engineering which is including design, procurement, construction and many other aspects.
