Surrounding total water resources control and the core of quota management of water resources management system, the economic structure system which adapts to the water carrying capacity, optimizing the allocation and efficient using water resources of engineering and technology system and the standard system behavior of the public conscious-saving, it has achieved remarkable results, the efficiency and effectiveness of water has significantly improved, water-saving awareness of the whole society is growing[1].
Theory and practice show that social organizations have indeed played a pivotal role in providing public goods and public services, perform the unique advantages in nurturing civil society and other aspects, is an important part of governance in today's society[6] .
Mutual cooperation and mutual restraint are between the different subjects , institution, and cultural ( awareness ) , information, technology, engineering , etc. constitute the external environment to run, each subject plays different roles.

The closure scheme optimization analysis of multiple large-span prestressed continuous beam bridges Jianming Hao1, a, Kaifa Zhou1,b 1School of Civil Engineering and Architecture , Chongqing Jiaotong University , China a123789247@qq.com, bkfzhou@cquc.edu.cn Keywords: multi-span prestressed continuous beam bridges, closure scheme, cantilever construction method, system transformation.
Closure scheme Advantage Disadvantage Engineering example 1 Close multi-span continuous system once ①Internal force changes more uniform ②Shorten construction period ③Avoid the increase of statically indeterminate times, make calculations simple ①Need more constructors and equipment； ②Tensioning closure strands will induce larger secondary internal force.
Take Wei river eight-span continuous beam bridge for engineering instance, this paper analyze the influences of eleven available closure schemes on internal force, stress and displacement of main girder, analysis shows that: 1.Using different closure schemes affect mid-span control section moment slightly in finished stage, the moment value is close to each other, but root section moment values have large differentials.
