El-Zahaby, Giza, Egypt About this Series Sustainable Infrastructure impacts our well-being and day-to-day lives. The infrastructures we are building today will shape our lives tomorrow. The complex and diverse nature of the impacts due to weather extremes on transportation and civil infrastructures can be seen in our roadways, bridges, and buildings. Extreme summer temperatures, droughts, flash floods, and rising numbers of freeze-thaw cycles pose challenges for civil infrastructure and can endanger public safety. We constantly hear how civil infrastructures need constant attention, preservation, and upgrading. Such improvements and developments would obviously benefit from ourdesired bookseries thatprovidesustainable engineering materials anddesigns. The economic impact is huge and much research has been conducted worldwide. The future holds many opportunities, not only for researchers in a given country, but also for the worldwide field engineers who apply and implement these technologies. We believe that no approach can succeed if it does not unite the efforts of various engineering disciplines from all over the world under one umbrellatoofferabeaconofmodernsolutionstotheglobalinfrastructure.Experts from the various engineering disciplines around the globe will participate in this series, including: Geotechnical, Geological, Geoscience, Petroleum, Structural, Transportation, Bridge, Infrastructure, Energy, Architectural, Chemical and Materials, and other related Engineering disciplines.

Such initiatives are also the core mission of the Soil-Structure Interaction Group in Egypt (SSIGE) to contribute to the ongoing research toward sustainable infrastructure. This confer- ence series “GeoMEast International Congress and Exhibition” is one of these initiatives. Ancientpeoplesbuilttheirstructurestowithstandthetestoftime.Ifwethinkin the same way, our currentprojects will bea heritage for future generations. In this context,anurgentneedhasquicklymotivatedtheSSIGEanditsfriendsaroundthe globe to start a new congress series that can bring together researchers and prac- titioners to pursue “Sustainable Civil Infrastructures.” The GeoMEast 2017 is a unique forum in the Middle East and Africa that transfers from the innovation in researchintothepracticalwisdomtoservedirectlythepractitionersoftheindustry. More than eight hundred abstracts were received for the first edition of this conference series “GeoMEast 2017” in response to the Call for Papers. The abstracts were reviewed by the Organizing and Scientific Committees. All papers werereviewedfollowingthesameprocedureandatthesametechnicalstandardsof practice of the TRB, ASCE, ICE, ISSMGE, IGS, IAEG, DFI, ISAP, ISCP, ITA, ISHMII, PDCA, IUGS, ICC, and other professional organizations who have sup- ported the technical program of the GeoMEast 2017. All papers received a mini- mumoftwofullreviewscoordinatedbyvarioustrackchairsandsupervisedbythe volumes editors through the Editorial Manager of the SUCI “Sustainable Civil Infrastructure” book series. As a result, 15 volumes have been formed of the final +320 accepted papers. The authors of the accepted papers have addressed all the comments of the reviewers to the satisfaction of the track chairs, the volumes editors, and the proceedings editor. It is hoped that readers of this proceedings oftheGeoMEast2017willbestimulatedandinspiredbythewiderangeofpapers written by a distinguished group of national and international authors. v vi Preface Publication of this quality of technical papers would not have been possible withoutthededicationandprofessionalismoftheanonymouspapersreviewers.The names of these reviewers appear in the acknowledgment that follows.

Ganesh Department of Civil Engineering, Indian Institute of Technology, Roorkee247667, India [email protected], [email protected] Abstract. Theactiveearthpressurecoefficientsanditsdistributionagainstthe face of an inclined wall retaining an unsaturated soil backfill, has been estab- lishedusingthelimitequilibriumapproach.Theanalysisisperformedwiththe help of a simple Coulomb-type mechanism. For different vertical unsaturated steadystateflowconditions,andthelocationofwatertable,thevariationofsoil suction stress that occurs within the vadose zone of the backfill soil mass has been taken into account in the analysis. The influence of different parameters such as inclination of wall, roughness and adhesion of soil-wall interface, ground surcharge pressure, properties of backfill soil and its flow conditions (infiltration, no-flow and evaporation conditions) on the active earth pressure, has been examined in detail. The depth of tensile crack has also been estab- lished. The active earth pressure in unsaturated sand is not affected with the variation in the flow conditions for given angle of internal friction of sand; whereas, significant variation in the magnitudes of active earth pressure in unsaturated clay has been observed with the change of rate and type of unsat- uratedflow.Theheightofwallandthelocationofgroundwatertablearefound to be the two prime factors that affect substantially the active pressure in unsaturated sand. On the other hand, for a given location of water table the magnitude of the active pressure in unsaturated clay is merely affected by the changeinthewallheight.Thesolutionsfromthepresentanalysisarecompared with the available theoretical results that are reported in literature for some special cases. 1 Introduction Determinationofactiveearthpressureexertedbyabackfillsoilmassisofconsiderable importanceinthesafedesignofanyretainingstructuresandhelpfulpartlyalsoforthe problems related to sheet piles, braced cuts and foundations etc. Most of the earlier studiesdealwiththisproblemassumingthebackfillsoilmassaseitherinastateoffully saturated or dry condition.
