Currently, the rock blasting theory and construction technology have matured and improved in domestic and international. Comparing to the land blasting, underwater explosion treatment of soft-based theoretical and applied technological research are lagging. In this paper, though the field trials and laboratory experiment carrying out treatment of soft-based technology research.In the field trials, with the test site of the project profile, geological conditions, hydrological conditions and characteristics of the project, presenting and summarying the construction of land-based Explosive Compaction Process. It is firstly using SH-2003G single bucket backhoe hydraulic excavator for the load-line cloth body medicine machine which charge device self-assembly R & D Assembled, proven drug use of this fabric laying machine construction of 10 drugs package only using 20-25min, construction of highly efficient. In the part of the used works, using before and after the explosion quality testing method, the volume balance method, hole drilling method of three ways to combine pairs of the seawall formed was conducted quality testing and assessed, through testing, levee is stable, in line with design requirements. Through studying the relationship between the amount of explosives, buried depth and the amount of riprap, it is obtained the relationship between the amount of explosives and the amount of riprap, the relationship between buried depth and the amount of riprap, so as to achieve the optimal choice blasting parameters to reduce the the purpose of construction cost. Heap of different amount of high explosive explosion, as well as exploration results obtained drugs in the buried depth and the same amount of explosive, the blast Ditou pile height increases the higher the better blasting results as well as the depth of buried drugs and Ditou Stacker the same circumstances, the greater the amount of blasting explosives, blasting effect is the better conclusion.In the laboratory experiment, using the law of explosion theory and the existing laboratory conditions,using single detonator exploded in the media pool with mud simulates the explosion of soft foundation treatment kits in a single explosion of the situation, two kinds of explosive approach to the consideration, distance from the explosion at different levels, the same depth, the same dose as well as with the same horizontal distance, the same depth,different dose of the explosion, in which the same dose from single the 8th industrial detonators to achieve, and different dose through laboratory specially designed single large dose of detonators to achieve, in order to allow more realistic simulation of laboratory tests the scene of explosion, special consideration of the interaction between multiple kits, finally, through the specially designed electrical test system were measured in all cases, the sludge medium wave blast and vibration waveform, the waveform interpretation of a series of data obtained through data processing and analysis, obtained under various circumstances the explosion shock wave overpressure, the vertical vibration velocity, the horizontal vibration of the speed of the calculation formula and a simple analysis of the explosive compaction mechanism, the formula of the correlation coefficients are 0.96 and above the basic line with accuracy of laboratory tests requested. The formula for the actual explosion of soft foundation engineering computing has certain reference value.Figure[43] table[37] reference[56]...
