To give the definition of the mass concrete and to concrete\'s cracks together with practical meanings of control ,and give a brief review on the research in the field at home and abroad, at last, methods to control temperature crack of the mass concrete from several aspects such as design measures,concrets material, construction schedules.etc are summed up; To explain the physical mechanics of the concrete and computing methods-Difference Method and Finite Element Method, and illustrate the application of their specific methods repectively;Several temperature factors that can influence the temperature stress of mass concrete baseplate are analyzed. The influence degree of temperature factor can be got through the ANSYS simulation computation the control of temperature can control the temperature stress, consequently control the temperature crack of mass concert baseplate; through the influence of the crack resistance ability of mass concrete baseplate which takes the reinforcement as a part is analyzed. By ANSYS simulation, the best suited volume ratio of reinforcement is found out, at same time the layout of reinforcement with the same volume ratio can also affect the resistance ability of mass concrete baseplate. Sum up of above analysis, anti-crack function of steel bar in early mass concrete baseplate is obvious, so it\'s necessary to consider beneficial effect of construction steel bar in research of temperature control on mass concrete baseplate.

The paper is based on the theory of inter-function between water and rock, and losing energy in rock mass, brought forward that the water flow has head loss during water flow intruding through the coal seam effective water-resisting layer and energy waste concept for splitting rock mass, and analyzed the form of the remaining water pressure. Through the simulation experiment in the preventing water capability of water-resisting rocks in the coal seam scaleboard, studied the law, character of the losing in water head waste and the relation to pressure, water-resisting of hydrogeology and engineering geology character. Brought forward the new method of calculating the water inrush coefficient.

Those rarely refer to the researches about water pressure function mechanism. In fact, the water flow intrudes upwards with a loss of the distance water and energy wastes for splitting rocks when confined groundwater intrudes upwards through coal seam water-resisting layer. The water flow under the coal seam scaleboard consumes more energy after it intrudes at a certain height.

At the same time, the relationship between the magnetic flux leakage signals and the physical characters (including the width、depth and position) of the corrosions are studied. The results identify that, if the floor is saturated, the magnetic flux leakage intensity changes linearly with the changing of the corrosion diameter. When the corrosion is in the surface, the peak value of the signal is higher than it's in the back.
