DESIGN OF SMALL DAMS CH. 5 Flashcards
THE INVESTIGATION FOR A POTENTIAL DAM SITE PRIMARILY CONSISTS OF 3 STAGES OR LEVELS OF STUDY. WHAT ARE THEY
-APPRAISAL
-FEASIBILITY
-DESIGN INVESTIGATIONS
THE PRIMARY CRITERIA FOR RIPRAP IS QUALITY AND SIZE
TRUE
WHY ARE STREAM DEPOSITS A GOOD SOURCE OF CONCRETE AGGREGATE
ALL OF THE ABOVE
IT IS IMPORTANT TO HAVE AN EFFECTIVE RES. GEOLOGIC MAP BECAUSE THE MAP IS ESSENTIAL FOR PLANNING AND CONDUCTING THE INVESTIGATION
TRUE
WHAT DO GEOLOGIC MAPS IDENTIFY
A-SURROUNDING AREAS
B-ROCK UNITS
AGRICULTURAL SOIL MAPS ARE USEFUL FOR ENGINEERING PURPOSES BECAUSE THEY PROVIDE DETAILED SOIL DATA AND INFORMATION RELATING TO DRAINAGE AREAS
TRUE
IN CONSTRUCTION OF FOUNDATION AND EARTHWORK FOR DAMS WHY ARE THE PHYSICAL PROPERTIES OF SOIL IMPORTANT
-UNIT WEIGHT
-PERMEABILITY
-SHEAR STRENGTH
WHAT HAPPENS IF SILT AND CLAY HAVE AS LITTLE AS 1O% OF THE PARTICLES IN SAND AND GRAVEL AND ARE SMALLER THAN THE NO 200 SIEVE SIZE THEY WILL BECOME SATURATED
FALSE
IN FIELD CLASSIFICATION IF THE SOIL IS GRAVEL IT CAN BE IDENTIFIED AS CLEAN OR DIRTY. WHEN DIRTY MEANS THAT IT HAS AN APPRECIABLE AMOUNT OF FINES
TRUE
STREAK MEANS IN REFERENCE TO ROCK THAT THE COLOR OF THE FINE POWDER OF A MINERAL OBTAINED BY RUBBING IT ON THE UNGLAZED PORTION OF A PORCELAIN TILE IS KNOWN AS ITS STREAK
TRUE
WHAT ARE THE MECHANISMS THAT DEVELOP SOIL DEPOSITS ON THE SURFACE OF SOIL
WATER, ICE, AND WIND
THE DEFINITION OF MODERATELY HARD ROCK IS THAT IT CANT BE SCRATCHED WITH A KNIFE OR SHARP PICK WITH LIGHT OR MODERATE PRESSURE
FALSE
WHAT ARE THE NON-ACCESSIBLE EXPLORATION METHODS FOR SUBSURFACE MATERIALS
ALL OF THE ABOVE
A VANE SHEAR TEST IS AN IN PLACE TEST TO DETERMINE THE UNDRAINED SHEAR STRENGTH OF A SATURATED COHESIVE SOIL
TRUE
