摘要： PROBLEM TO BE SOLVED: To provide a method for estimating geology in front of a facing of a tunnel which enables accurate estimation of the state of the geology in front of the facing.
SOLUTION: A fracture energy factor is calculated from the data obtained by drilling a drill bed-inspection boring hole 9 in front 13 of the facing, while a bedrock strength and an excavation volume-ratio energy are calculated from the TBM machine data obtained by excavating a bedrock 1 by TBM 3. The fracture energy factor is converted into the bedrock strength and the distribution of the bedrock strength is modeled by a function containing information on a position, such as a mean value function or a covariance function. Based on a model thus obtained, the bedrock strength at an arbitrary point is estimated by using kriging.

摘要： PROBLEM TO BE SOLVED: To provide a permeability test evaluation system and a permeability test evaluation method capable of estimating a hydrogeological structure with high accuracy from the result of a cross hole permeability test executed in a homogenous base rock having complicated bleeding channels independently from an initial mode. SOLUTION: After the permeability test of a ground 39 is performed to acquire a head diffusion coefficient 63 between observation points, the constellation 41 of observation points A, B to J is determined by using the inverse of the head diffusion coefficient 63 as similarity in a multi-dimensional scaling method. A point group 45 is arranged at uniform density within a polygon 44 having the constellation 41 of the observation points as an apex and a center of gravity matched to an origin, in which the square of the difference between the constellation 41 of the observation points and a position 46 in a real space of the observation points is minimized. Geometric reconstitution is performed by use of inverse distance interpolation so that the constellation 41 of the observation points is moved to the position 46 in the real space of the observation points, and the density of the point group 45 is measured for the real space, whereby a hydrogeological structure model is formed.

摘要： PROBLEM TO BE SOLVED: To properly predict geological condition on the front side in a tunnel and the like to be dug for preparing a countermeasure against a defective geologic part part previously so as to safely perform construction economically by means of a combination of four processes such as TSP, drilling logging, speed logging, and facing image processing. SOLUTION: In advance examination of a tunnel to be dug by means of a facing front survey general system, elastic wave velocity of the natural ground is measured along a track and approximate position and dimension of a fracture zone are estimated. From this information, a survey requiring section in front of the facing is determined, and firstly, existence of a surface of discontinuity to a predetermined distance in front of the facing is predicted according to an elastic wave research reflection method. When the facing approaches the surface of discontinuity, drilling logging is carried out while using a hole bored by a drill jumbo, and a fracture energy coefficient is found. Then, speed logging is carried out in the hole, in which drilling logging is carried out, and a geological condition is predicted on the basis of the elastic wave velocity. If a correlative relationship between the elastic wave velocity and the fracture energy coefficient is confirmed, from then on, a geological condition is predicted only by drilling logging.

摘要： PURPOSE:To successfully deal with the weak point of a conventional construction method by a method wherein a ground is excavated down to a given depth from the upper layer of the central part of a scheduled underground structure to build a vertical shaft, and a space is constructed in a ground from the vertical shaft serving as a starting point by a shield construction method. CONSTITUTION:A shield machine is radially augered gradually downwardly from a vertical shaft 1 to form a tubular shaft part 4 serving as the shaft of a roof R of an underground structure. A bedrock between the adjoining shaft parts 4 is horizontally excavated continuously throughout a range of from a base end on the vertical shaft 1 side to the tip of the shaft to form tubular roof tubes with which the roof R is formed and form the roof part R. After or simultaneously with formation of roof tubes 5, a side wall W is built in the shape of a cylinder vertically downward from the roof tube 5 on the tip side of the shaft part 4, serving as a base. This method enables reduction of the area of the occupied site of a ground and enables suppression of an influence exercised on a ground to a minimum value.
