Surface-consistent statics using simulated first break is proposed so as to cope with the tough problem in data processing which is caused because near surface seismic velocity increases with dune thickening in Xinjiang deserts. This method makes full use of all first arrivals(i. e. the first break informations of direct wave,reflected wave and refracted waves in multiple layers)instead of usual fitst break refraction statics,so that the accuracy of statics is improved. Simulated first break times are obtained...

Surface-consistent statics using simulated first break is proposed so as to cope with the tough problem in data processing which is caused because near surface seismic velocity increases with dune thickening in Xinjiang deserts. This method makes full use of all first arrivals(i. e. the first break informations of direct wave,reflected wave and refracted waves in multiple layers)instead of usual fitst break refraction statics,so that the accuracy of statics is improved. Simulated first break times are obtained by fitting exponentially the average of first break times picked form each shot. Thus the simulated first break curve only indicates relation among thickness of near surface layer,velocity and offset,without noises and surface influence included. The ability of automatically picking up first break times is improved because of the use of fitting method. It is a practical method for calculating big static correction values.

为了解决新疆沙漠地区近地表速度随沙丘厚度增加给地震资料处理造成的困难,提出一种模型初至地表一致性静校正方法。此法不采用传统的初至折射静校正的概念,而是充分利用全部初至波(包含直达波、反射波和多层折射波的初至信息),因而提高了计算静校正的精度。模型初至是利用指数形式拟合各炮拾取的初至时的平均值取得的,因此所确定的模型初至曲线平滑掉了各种干扰和地表变化的影响,仅包含近地表的地层厚度和速度与炮检距的变化。由于此法采用了拟合计算方式,从而增强了自动拾取初至的能力,它是一种有效而实用的大静校正量的计算方法。

The present situation on development of off-road vehicles used in desert in this country is reported in this paper. The desert crossing capability tests of domestic off-road vehicles have been carried out in Xinjiang desert area compared with various other vehicles made in U. S. A. and Japan, etc., the experimental results are studied and compared.

Among various assumptions of tyre and soft soil contact contour, the concept of equivalent rigid wheel introduced by Fujimuto in 1977 is widely used. Generally, the concept is used in interaction of tyre and clay soil; in this paper, it was developed for use in the interaction of tyre and sand. For this purpose, the tangential displacement of sand under the tyre was analyzed first and then the prediction model for the interaction of tyre and sand was proposed. Furthermore, in the prediction model the effects...

Among various assumptions of tyre and soft soil contact contour, the concept of equivalent rigid wheel introduced by Fujimuto in 1977 is widely used. Generally, the concept is used in interaction of tyre and clay soil; in this paper, it was developed for use in the interaction of tyre and sand. For this purpose, the tangential displacement of sand under the tyre was analyzed first and then the prediction model for the interaction of tyre and sand was proposed. Furthermore, in the prediction model the effects of loading modes on sand pressure sinkage relation was considered. In order to verify the prediction model, an electronic experimental device for measuring tractive performance of vehicle was developed, and the tractive test was carried out in Takelamagan Desert in Xinjiang. The results show that the predicted values of tractive efficiency and tractive coefficient are in conformity with the tested ones.
