The writers had the great pleasure of working with Professor Seed on the research described in this paper. He played an active role in these studies, which were begun in the early s Wong, Duncan and Seed, , and continued later under a contract for the U. Anny Corps of Engineers Wright and Duncan, We are pleased to acknowledge Professor Seed's great influence on and conuibution to this work, and to dedicate this paper to his memory. When the water level outside a slope drops, the stabilizing influence of the water pressure on the slope is lost. If the water level subsides so rapidly that the pore pressures within the slope do not have time to change in equilibrium with the drop in external water level.

Interaction between seepage field and soil stress field influences soil effective stress in general consideration. In addition, water erosion in soil skeleton can also affect soil effective stress. The current studies conducted triaxial compression experiments with seepage, Duncan-Chang model analysis, ABAQUS numerical simulation and followed by a case study analysis. Experiments show that the water erosion in soil skeleton reduces effective stress strength of soil, which is quantitatively described by the reduction of equivalent confining pressure. Through analyzing the characteristics of soil stress-strain curves, the equivalent confining pressure is applied to improve Duncan-Chang model.

UTexas4 is a computer software application for computing the stability of earth and earth-rock slopes and embankments. Stephen G. Wright of Shinoak Software, who is well-recognized as one of the leading experts in solving problems in soil strength and slope stability Duncan and Wright, UTexas4 has been considered one of the most sophisticated commercial software available to study the stability of slopes using a two-dimensional, limit-equilibrium method.
The Engineering Community. Evaluating the stability of slopes in soil is an important, interesting, and challenging aspect of civil engineering. Concerns with slope stability have driven some of the most important advances in our understanding of the complex behavior of soils. Extensive engineering and research studies performed over the past 70 years provide a sound set of soil mechanics principles with which to attack practical problems of slope stability. The objective of this book is to draw together some of the lessons that have been learned about measuring soil strengths and performing limit equilibrium analyses of stability into a consistent, clear, and convenient reference for students and practicing engineers.
Он не скрывал от нанимателей того, что случилось с ним во время службы в морской пехоте, и стремился завоевать их расположение, предлагая работать без оплаты в течение месяца, чтобы они узнали ему цену. В желающих принять его на работу не было недостатка, а увидав, что он может творить на компьютере, они уже не хотели его отпускать. Профессионализм Хейла достиг высокого уровня, и у него появились знакомые среди интернет-пользователей по всему миру. Он был представителем новой породы киберпсихов и общался с такими же ненормальными в других странах, посещая непристойные сайты и просиживая в европейских чатах. Его дважды увольняли за использование счета фирмы для рассылки порнографических снимков своим дружкам.
Все трое как завороженные смотрели на это зрелище, не лишенное какой-то потусторонней величественности. Фонтейн словно окаменел. Когда же он пришел в себя, его голос был едва слышен, но исполнен решимости: - Мидж, вызовите аварийную команду.
Это нацарапал мой дружок… ужасно глупо, правда.
