Title: TRENDS
Accession Number: 00235704
Record Type: Component
Abstract: SOME OF THE CHANGES AND IMPROVEMNTS THAT ARE NEEDED IN PREVENTING LANDSLIDES ARE DISCUSSED IN THE FOLLOWING CATE- GORIES: (1) ECONOMIC AND LEGAL ASPECTS, (2) LANDSLIDE TYPES AND PROCESSES, (3) FIELD RECOGNITION AND AIRPHOTO INTERPRE- TATION, (4) FIELD AND LABORATORY INVESTIGATION AND STABILITY ANALYSES, AND (5) PREVENTION AND CORRECTION. LEGISLATION PASSED BY THE CITY OF LOS ANGELES CONCERNING GRADING, EXCAVATION, AND FOUNDATIONS IS RECOMMENDED FOR SIMILAR LEGISLATION BY OTHER CITIES, AND PERHAPS EVEN FOR COUNTIES AND STATES. THE ANTICIPATED INCREASE IN EMPHASIS ON PREVENTION OF SLIDES SHOULD LEAD TO A MORE GENERAL AGREEMENT ON A SINGLE SYSTEM OF CLASSIFICATION. MORE RESEARCH IS NEEDED INTO THE BASIC PROPERTIES OF DIFFERENT MATERIALS AS RELATED TO ENVIRONMENT. ADVANCES IN AERIAL PHOTOGRAPHIC TECHNIQUES AND EQUIPMENT ARE BEING MADE BECAUSE OF THE EMPHASIS ON RECOGNITION OF POTENTIAL LANDSLIDES. THE MOST FERTILE FIELDS OF THE LANDSLIDE PROBLEM FOR RESEARCH AND DEVELOPMENT ARE SEEN AS THOSE OF FIELD AND LABORATORY INVESTIGATIONS AND QUANTITATIVE ANALYSES OF STABILITY. THE MAJOR PREDICTION OF A SHIFT IN THE FUTURE FROM EMPHASIS ON CORRECTION TO PREVENTION IS DISCUSSED. A BETTER UNDERSTANDING OF THE FORCES INVOLVED IN THE LANDSLIDE SHOULD ELIMINATE SOME OF THE FAILURES WHICH HAVE OCCURRED THROUGH THE MISUSE OF PILING AND RESTRAINING STRUCTURES. THE EXPERIENCE GAINED AND RECORDED IN THE FILES OF MANY HIGHWAY DEPARTMENTS AND OTHER AGENCIES NEEDS TO BE ORGANIZED AND ANALYZED.
