Grout age: enter grouting and test dates

Verification pending. Enter project-specific requirements and measurements.

The grade is a nominal strength designation, not a tested grout strength. Grout age does not automatically prove readiness. This section does not adjust modeled grout–ground bond capacity.

GROUNDWATER / HORIZONTAL DRAIN

Water observed at drain? Flow condition Drain reference Measured discharge (L/min), optional

Groundwater observation not recorded.

Discharge at a horizontal drain does not determine pore pressure or the groundwater level along the nail. No automatic bond-strength reduction is applied.

ENGINEER-REVIEWED GROUND BOND INPUTS

Optional site-specific grout–ground resistance (kPa) for every active ground material. Default model uses illustrative assumed values. Approval name, technical basis and an explicit activation are required. No automatic correction based on grout age, strength, pressure or groundwater.

Engineer / reviewer Review basis / test reference Use reviewed q values in mechanical simulation

DG1: threaded bar displacement. DG2: bearing plate seating/movement. Actual gauges must use stable independent supports, not attached to the moving jack or plate. Verify on site.

Calibration Review

Select matching project and soil profile. Only a confirmed soil/grout bond pull-out failure produces a measured ultimate average bond resistance. A no-failure result provides a demonstrated lower bound, not an ultimate strength.

Average observed ultimate bond—kPa · not a design value

Illustrative model inputs must not automatically become accepted design parameters. Review failure mode, geology, construction method, test bond length, representativeness, scatter, partial factors and project specification before approval.

Verification Summary

Status compares the recorded results with the limits you enter; it is not an automatic professional certification. PASS requires a valid approved reference, achieved proof load, verified hold and every provided movement/creep limit to be satisfied. Missing required measurements remain pending.
