Introduction For the pile foundation frost heave in seasonal frozen soil region, the Institute of Water Conservancy and Science in Heilongjiang province has done a lot of research on pile foundation antifreezing measures.
In the practical engineering application, in order to avoid some powder material invading the aeolian sand scope due to water flow in a horizontal, vertical seepage, then reduce the aeolian sand antifreezing effect, it should be around in sand and surface with plastic film, to ensure that the frost heaving effect of pile foundation filled aeolian sand long-term stability.

Peel away the fiber sheet material that damage specimens stuck outside, found in the fiber cloth surface sticks has the 2-5 mm mortar, this suggests that fiber cloth and concrete have enough bonding strength between them; Internal core concrete has nearly pressure crisp, but the shape keep intact; Central to the concrete specimens are obviously a drum, has completely crushed and with the core concrete completely separated, seen in Fig. 3.

Introduction Urban ecosystem is a special kind of human-centered artificial ecosystems, is the city's natural, economic and social sub-systems consisting of an organic complex, with common difference is that natural ecosystems, urban ecosystems, human-centered, man-made changes in its structure, material recycling and energy conversion methods, long-term impact of human activities by terrestrial ecosystems[1].Scientific assessment urban ecological system, figuring out the current values of individual indicators, comparing with the standard or reference target, identifying gaps, analysis the causes, determining the future direction of the building to develop effective strategies is important path to build eco-city[2].Evaluation of urban ecosystem is a complex systems engineering.
Through the establishment of data warehouse, data stored together with the evaluation algorithm can not only accurately be assessed efficiently conclusion, you can also use data mining techniques to predict the future trends in science for decision making.

The relatively mature multi-objective genetic algorithm is a kind of searching method of imitate biological evolution based on stochastic theory and has been widely used in various science fields in recent years [6-9].
While a beam structure with variable cross-sections can solve this problem, which is capable of fitting the deformation curve well and reducing material cost as well.
