Continuously reinforced concrete pavement (CRCP) completely no expansion joints and contraction joints ( construction joints and expansion joints required except construction ) , greatly improving the flatness of the road and the overall strength and cars with smooth , while reducing maintenance costs long life, so it has great prospects for development , but because people recognize prejudice and cracks higher investment costs and slow development . Currently a large number of foreign research model , but there are limitations , does not comply with China 's national conditions , so there is need for the current lack of research on the mechanical model CRCP -depth , systematic research, establish a more complete mechanical model , which has an important theoretical value and practical significance. This large number of domestic and foreign CRCP reference model , learn from the temperature gradient and humidity gradient methods , considering the temperature variation in the thickness of the plate surface and warping effects of proposed non-linear temperature distribution into a linear temperature distribution , the humidity gradient converted to the temperature gradient is calculated. On this basis , considering the load transfer between the cracks , asphalt and curbs mezzanine impact ABAQUS finite element simulation software through the introduction of a spring element to simulate the load transfer between the cracks , and introduced the spring stiffness and load transfer conversion method . Equivalent Equivalent steel and thickness proposed concepts and methods , and its reliability demonstration, draw an equivalent formula , which greatly simplifies the calculation model ; through geometry, unit selection, boundary conditions , load conditions, the simulation model calculation parameters discussed , draw on the results of the important parameters were investigated. Consider load transfer coefficient between the cracks , the crack spacing , temperature gradient and the thickness change , given vehicle load , temperature gradient under CRCP nomogram stress analysis and nomogram given query design case . Analysis of the thrust generated by the mechanism of the thrust prediction program, which takes into account load transfer coefficient loss , fatigue damage of concrete and other effects , given based on non- uniform distribution of transverse cracks thrust estimation method . Analysis of the test road conditions and CRCP construction technique to study the strain and deflection testing methods, and in accordance with the reality test road conditions and test results to establish mechanical model , and ultimately the results of the test applied to the mechanical model , a more realistic reflection of the road the true situation.
