The Analysis of the Influence of the Bore Hole on the Statio Sounding Curve in the Strata of Holocene Epoch in Quaternary
Zhao Jingming
1993, (2): 1-4.
[Abstract](31) [PDF 3529KB](8)
Abstract:
Based upon the analyses of engineering cases, the bore hole influence on the static sounding curve in strata of Holocene epoch in Quarternary period in Wuhan city is discussed. And a suggestive distance between the sounding hole and the bore hole is put forth for the combined holes in various soil strata as the bore hole is finished before the static sounding hole.
The Forecast of the Deformation and Failure of Slopes by Grey Theory
Li Hongyi
1993, (2): 5-12.
[Abstract](31) [PDF 6262KB](8)
Abstract:
According to the law of deformation of landslide, the grey forecast GM(1, 1) based on the site observing displacement is built up in this paper. And the forecast model for landslide is set up accoroding to the grey Verhulst model of the deforming rate. Accordingly, the deformation and deforming trend of future can be calculated, and the landslide can be forecasted, The theory, and色principle i of this method is expound,0 It is emphatically expounded that 父the optimization processing of data and the inspection and revision of the model, This文method is质:verified by landslide cases.

1993, (2): 13-20.
[Abstract](38) [PDF 7083KB](8)
Abstract:
The new methods of geotechnical calculation and structural design for cantilever retaining bored cast in-place piles are proposed in this paper. Some problems about the geotechnical investigation、design and construction of this pile are discussed
The Classification and Characteristic of the Building Ground in the Area of Guizhou
Yuan Wan
1993, (2): 21-24.
[Abstract](29) [PDF 4317KB](12)
Abstract:
The main building ground is classified based on the certain rock properties of strata、geological structure、topography and geomorphy、meteorology、and hydrology condition and engineering activities in the Guizhou province. The engineering geological characteristics of various ground are expounded to have some references for the surveying、2 designing and construction of geotechnical engineering.
The Application and Design of the Flexibity Pile
Chen Qun
1993, (2): 25-27,31.
[Abstract](39) [PDF 3784KB](8)
Abstract:
The function in the ground improvement of the flexibity pile and the selection in the application of various ground, and the design of the pile length and the replacement rate of pile are discussed in details in this paper. And the method to calculate the bearing capacity of composite ground by using the bearing capacity of pile and soil is also introduced in this paper.

Pit Water Blowing Predication Using the Theory of Grey Control System
Su Wenzhi
1993, (2): 35-37.
[Abstract](27) [PDF 2825KB](7)
Abstract:
The analysis method of grey control system is applied in the pit water blowing predication in this paper. The predicative model of pit water flow for Furong Coal Mine of Sichuan Province is set up.And the quantity of blowing water is predicated and analysed. Based on the predicated results of water blowing, the basis for the desiging of drainage method is proposed.
Disscassions on Some Problems in Applications of the Management Model of Groundwater
Shi Ruiqing
1993, (2): 38-42.
[Abstract](29) [PDF 4478KB](10)
Abstract:
The applicability and the resolve method of the respond matrix method in the management model of groundwater resources is discussed in this paper, And the selection of the length of the control time segement is also discussed, and compared with some examples.
Surveying Engineering
The Probing of Subsurface Line Pipe and the Analysis for the Data
Peng Wulin
1993, (2): 43-48.
[Abstract](24) [PDF 6071KB](8)
Abstract:
The Probing of subsurface line pipe is very important in engineering surveying, and is also a work with much difficulty. Some experience and realization about the probing of author are proposed in this paper to interchange with fellows, so to accelerate the developement of the surveying of the subsurface line pipe.
The Theory of Static Quickly Locating of GPS and its Experimental Analysis
Ge Maorong
1993, (2): 49-51.
[Abstract](37) [PDF 2621KB](5)
Abstract:
The theory of static quickly locating of GPS and the software QHGPPS compiled by this theory are described in this paper. The application to the Trimble 4000 SST double frequency GPS receiver of this software is introduced. The results proved that this software may achieve the degree of precision of millimeter only taken 10 minutes to receive 5 satellites in same frequency within 10km.
Discussions on the Optimum of Distance Surveying Wire of Electromagnetic
Huang Dijin
1993, (2): 52-59,64.
[Abstract](25) [PDF 7954KB](5)
Abstract:
When S > 400m, b> 5 (bs/n) and the certain relationship of fa~s,fa~b, fs/[s]~[s] and fs/[s]~b are exist, the best results under the same observing precision are obtained. Above conclusions are proposed based on the studies to the results of 33 distance surveying wires of annexed electromagnetic wave. The optimum value of[s] and n, the selection of begining azimuth is also proposed in this paper, it has some reference value for surveying of annexed wire.
