OBJECTIVE: To explore three-dimensional reconstruction of hepatic portal vein by laminagraphy of cast specimens to provide anatomic basis for hepatectomy.
When the regional extension is disharmonic with the basement structure and movement, complicated fault assemblages can be form during progressive deformation.
In order to ensure safety in nuclear power plant,must according to capital construction procedure,complete one's work of prospecting,especially give and appraisal of paraclase.
Methods The serial sheet transverse sections of the superior orbital fissure region obtained using collodion microtomy in 5 adult cadaver heads were observed.
On basis of this model, the modeling methods and modeling flow were discussed based on data source of geological observation, drillhole, ichnography and section map.
Cross-section of slip distribution. the strike direction of fault plane is indicated by the black arrow and the hypocenter location is denoted by the red star.
This is the formula for a thick vertically faulted slab with such a large throw that the downthrow side makes no contribution to the gravitational force .
From the analysis of the faults distributing characters,the main part of faults have two group normal fault system with "lambdoidal shape"and trending towards to NE and NS separately.
So the distribution and the content of conglomerate were different, and its geological phenomenon in the data of drilling, outcrop, logging and seismal section in different area.
This paper presents an efficient method of modelling jointed rock by using the boundary ele-ment method via the concept of multiregion and non-linear model of joint and fault.
In addition, it is a principle to follow that the formation thickness of upfaulted block is greater than or equal to the downdip block in correlation of subzones as facing faults.
