摘要： A device and method for monitoring freezing-thawing damage of an underwater concrete member in situ. A main structure includes an upper link, concrete member, transverse sealed box, longitudinal sealed box, movable guide rod, probe launching box, multichannel data collector, frequency modulation transmitter, computer, auxiliary wheels, lower link, and a wireless temperature sensor. A process includes four steps: launching of a probe, collection of data, calculation of an elastic modulus, and evaluation of freezing-thawing damage. The device is simply structured, easy to operate, and can be reused, and provides power for launching the probe by non-contact force transmission by using high-strength magnets of the same pole, resolving the sealing problem, and calculates the elastic modulus of the concrete member by using acceleration data obtained by a probe, so as to obtain a loss amount of the elastic modulus, thereby performing real-time in-situ monitoring for freezing-thawing damage of an underwater concrete member.

摘要： The present application belongs to the technical field of monitoring of durability of concrete, and particularly relates to a method for optimizing a structure of an electrical capacitance tomography sensor and analyzing an electromagnetic field. A specific process of the method includes eight steps: parameter setting, geometric setting, material setting, mesh generation, physical field setting, solution, sensor structure optimization and calculation of electromagnetic field distribution. The method proposes a new concept for solving a forward problem of an ECT system based on COMSOL software. After modeling is completed, uniformity of a sensitive field of the ECT sensor is analyzed according to calculation results, and structural parameter values of components of the ECT sensor are adjusted to seek an optimal design scheme.
