| Natural hazards not only destroy people's living environment, but also threaten,even bring huge loss to, the safety of people's lives and fortune. Landslide is one kindof serious natural hazard, which happens frequently with an extensive distribution inChina. Thus, it is very meaningful to research the integrative analysis and designprogram of landslide control. The production of this essay is the integrative designprogram of computer automatic searching the sliding surface of pre-slide body andanti-slide pile design, which can actualize the automatic searching the critical slidingsurface of slope, stability analysis of the slope with sliding surface, work out theinternal force calculation results of anti-slide pile, export corresponding results bydocuments and design pictures respectively.Computer Technology, Theory and Experiment are becoming the three mainstaysof every subject nowadays. Theory is the basic guide of subject development.Experiments, in particular the repetitive ones, are the fundamental validation of whetherthe theory is correct or not. Computer Technology makes it the most efficient that theorybeing involved in application. Goetechnical Engineering Digitalization, also namedGoetechnical Engineering Virtual Design System (VDS), is a technology newly broughtforward, which even is at a higher level than Goetechnical Engineering Design. VDScombines the participation of Goetechnical Engineering Virtual Reality andGoetechnical Engineering Virtual Reality Technology, which has produced great harvest,just as other virtual technologies, becomes one of the several main technologies thatmay make the severe variation of the society come into being in the 21 st century. Thelevel of research and application directly affects national defense, economy, science,education and other aspects, even includes the synthesis national power of a country."Getting behind always means taking a beating". The Digitalization Technologyrecounted in this dissertation is about the idea of my supervisor Professor Boyang Ding,which, by applying the computer technology in existence, based on DB technology,integrates the alternating goetechnical engineering design software with innovation,accomplishes the integrative engineering design of virtual site.To accomplish the goal recounted above, based on synthetical comparison ofadvantages and disadvantages of many methods on sliding surface searching, aninnovative method of searching the critical sliding surface on the entire slope gridding is brought forward in this essay, which is a geometrical optimization method on slopegridding. It can be the same with the multi-mode search of complex slope, and theanalysis results of safetv coefficients are quite holistic and stable. So long as programuser inputs the necessary datum required, the critical sliding surface would be searchedout by the program. To complex slope, it also gives out the possible sliding surface ofthe local failure and its relevant safety coefficient, which would make it easier that thedesigner or researcher, according to the factual situation, makes out the more precisejudgement and appraisement of stability of the slope. It also can work out the safetycoefficient of the slope with known sliding surface or the intersection point of slidingsurface and the slope surface.There are two approaches, soil pressure combining transmit-coefficient slicemethod and soil displacement combining simplified Bishop method, applied in theanti-slide pile calculation. To each approach, it also provides three numerical calculationmethods of free pile head, nonrotational pile head and anchor bar respectively.At last, taking a landslide of K103 part of Hang-Jin-Qu highway as an engineeringcase, it presents the whole process of modeling, calculation and picture and documentoutputting. The result derived by this program is compared with the result fromcommercial software "Lizheng", which verifies the correctness of the program.
