| The hazard of our society has been introduced by settlement of inspection chamber in road, and the fee of maintenance and overhaul are incrementing every year. Therefore, settlement of inspection chamber is noticed by scholars of foreign and home.In this dissertation, on the basis of the existing work, constant cross-section inspection chamber and variable cross-section inspection chamber have been studied with a totally new approach. Afterwards, two solution are contrasted, and the latter solution is using in practice project. The main original work includes:Settlement of inspection chamber under traffic loaded has relation to interacting of soil and road. On the basis of fundamental assumption, this dissertation establishes longitudinal vibration equation of constant cross-section inspection chamber through analyzing. And then, analytic solution of inspection chamber is gained by using of separation of variables. Last, influencing factors of vibration settlement are founded through studying settlement curve.And then, this dissertation analyze variable cross-section inspection chamber, owing to the former method only appliances constant cross-section inspection chamber. On the basis of fundamental assumption, this dissertation establishes longitudinal vibration equation of vibration cross-section inspection chamber through analyzing. And then, analytic solution in Laplace domain of inspection chamber is gained in this dissertation by using of integral-transformation method and impedance function. And, half- analytic solution in time domain of inspection chamber is gained by using of convolution theorem and inverse Fourier transform. Last, influencing factors of vibration settlement are founded by studying five settlement curves.In front, this dissertation has gained analytic solution of constant cross-section inspection chamber and half-analytic solution of vibration cross-section inspection chamber. Then, two methods are compared with each other in theory and settlement curve, as a result, the latter method can analyze practice problem. Last, thisdissertation uses latter method to practice project, and takes improvable inspection chamber that can effectively reduce settlement. |
