The model of the thesis s forecasting method is synthetical use of experience model method and mine-reserach information adding power model method of mineral resources assessment based on GIS. It use several kinds of analysis means for multi-sources data. Firstly the gold-research prospective domains of this area are forecasted through the spatial query and ana-lysis by means of GIS,based on geological and mineral information of thearea, synthesizing geochemistry anomaly information. Gridding inserting value transforms geochemistry data of sampling point of the south of Acixiarega from scattering data to grid data by means of the development of Delphi and Mapobjects, using distance reciprocal inserting value method. After deposit orientation analyse and spatial overlapping analysis by means of CIS, the gold-research prospective domains of the area are forecasted.

Its amount has relation with acting load. The influence on sectional curvature of bending components is the greatest one, the ultimate curvature of corroding section decrease obviously, and the sectional curvature increases rather sharply with the increase of rust rate during the process of corrosion. The anti-cracking capacity of prestressed bending R. C. components may be damage. For the convenience of engineering usage and damage evaluation of structure, this paper presents a concept of sectional damage coefficient on the foundation of experimental and treatment study.
试验与理论研究均表明,受压区钢筋锈蚀后对普通钢筋混凝土和预应力钢筋混凝土受弯构件的承载力影响均不大,但对构件的正常使用性能有较显著的影响,受压区钢筋锈蚀过程中,截面刚度有较显著的下降,挠度及受压区混凝土压应变随锈蚀量增加而增加,增加值与使用荷载大小有关;受弯构件的截面曲率所受影响最大,锈蚀后截面的极限曲率有明显的下降,在使用荷载作用下,截面曲率则随钢筋锈蚀量的增加而有较显著的增加;而预应力混凝土受弯构件的抗裂度会下降。
