CRP vs MLT -- dalam keadaan bagaimanakah CRP ini digunakan?

Question

STANDARD SPECIFICATIONS FOR BUILDING WORKS (2005 Edition)

 

2.6 Maintained Load Test

A loading test in which each increment or decrement of load is held constant either for a

defined period of time or until the rate of settlement or rebound falls to a specified value.

 

2.7 Constant Rate of Penetration Test (CRP)

A loading test in which the pile is made to penetrate the soil from its position at a constant

speed while the force applied at the top of the pile to maintain the rate of penetration is

continuously measured, until the force versus penetration relationship obtained does not

represent an equilibrium condition between load and settlement.

Answer 1

Saya biasa dengar MLT dan Dynamic Load Test tetapi belum pernah tentang CRP. Berminat untuk mengetahui lanjut tentang CRP dan samada JKR pernah menggunakan kaedah itu dimana2.

Comments

Difahamkan CRP akan dikeluarkan dari spesifikasi dan akan ditambah dynamic load tests.  Tidak dapat dipastikan bila spesifikasi baru akan dihasilkan.

Answer 2

CRP sudah tiada lagi di dalam Standard Specification for Building Works 2014.
