Land subsidence assessment on karst based on resistivity and geotechnical parameters
نویسندگان
چکیده
Karst is geomorphologically composed of limestone. However, limestone very susceptible to weathering due the influence water, which can cause land subsidence. The resistivity method often used determine potential for subsidence, while geotechnical methods are commonly considered capable juxtaposing with support interpretation accuracy. current research was conducted subsidence in karst area Lappae, South Sulawesi, Indonesia. utilizes a dipole-dipole configuration, and parameters uniformity coefficient, curvature water content, shear angle, cohesion. results obtained be classified into northern southern areas. classification these areas based on results, show high values (> 4800 Ωm) part. This value assumed feature cave. Caves predominantly distributed five that part, massive (150-1600 Ωm), stable area, though it highly prone landslides. As suggest presence caves primary factor contributing landslides this region. These indicate that, evaluation location, not feasible use. In addition, spite low cost rapid methods, combination shows good results.

Analysis of Factors in Land Subsidence in Shanghai: A View Based on a Strategic Environmental Assessment
It has been observed that in the urban center of Shanghai, land subsidence has accelerated, and the groundwater level has continued to drop even though the net withdrawn volume (NWV) of groundwater has remained unchanged since 1980. An analysis of monitoring data shows that drawdown of the groundwater level is one of the factors that have influenced land subsidence since 1980. The NWV of ground...

in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
